Pricing: what it costs, and how much

Everything I can do for you, with the price next to it. What you buy straight away has an exact figure; custom projects have a floor, because the quote depends on what you actually need.

How to read this price list

Prices are exclusive of VAT and of any applicable taxes. The exact amount, including applicable taxes, is shown in the summary before payment and on the invoice.
The figures for custom projects are thresholds, not quotes: the precise quote comes after the free discovery call, once the scope is clear to both of us.
This price list is valid until further notice. If you are reading a cached version, the latest one is always on this page.

Fixed price, you buy it right away

These figures are what you pay. No negotiation, no mandatory call first: you choose, you pay and you start.

MVP to validate an ideaYou have an idea and you don't know whether the market wants it. Before investing in a final system you need an answer made of usage data, not a mockup.	A working application in production with the essential features, user accounts and payments if needed, usage measurement and documentation so anyone can take over the code. Typically 6-10 weeks	from €16,000per project	Let's discuss it in discovery
Custom management software for your SMEYour processes live in spreadsheets and in software that does not follow the way you work, and a generic ERP costs too much and forces you to change habits.I have not yet delivered it to an external SME. That is why, on the first management system for an external client, I offer favourable terms in exchange for a reference, to be agreed in discovery.	Modules built around your real processes, users with role-based permissions, reports on the numbers that matter, exports for your accounting and training for your team. Typically 8-14 weeks	from €13,500per project	Let's discuss it in discovery
An iOS and Android app for your serviceYour users live on their phone and a site opened in a browser is not enough: you need an app in the stores, one that sends notifications and keeps working when the network drops.The mobile app lives inside a product of my own: I have not yet delivered one as a mobile project for an external client. On the first one I offer favourable terms in exchange for a reference, to be agreed in discovery.	A single codebase published on the App Store and Google Play, with access to device features through native plugins, push notifications, offline sync, deep links into the app screens and the backend that powers it.

A complete web app with the AI feature built into the workflow (search over your documents, summarisation, classification), the model running on your own hardware with Ollama and a defined behaviour for when the model is unavailable.

Open it and checkThat project is from 2025 and runs on a hosting setup different from the one I would use today: I am telling you because if you open it and look at the response times, you are not looking at my current stack.

Platform for an association or non-profitOnline membership with payment, a members-only area, event management: association life that stops living on paper forms and spreadsheets.The proof OnStage APS, Botrugno: a platform in production with online membership, members' area, event management and community features. The repo does not state whether that collaboration was paid work, so I do not present it as a paid commission.

Integration, infrastructure and maintenance

Integration, infrastructure and maintenance — What happens around the software: making it talk to the rest, keeping it up, carrying it forward after release.
Item	What is included	Price	Action
Making the systems you already have talk to each otherBack-office tool, e-commerce, accounting and CRM exchanging data on their own, instead of being realigned by hand every week. Without replacing anything.This is where my proof is missing: I have built integrations inside my own systems, not between a client's systems. A fixed price on an integration whose endpoints I have not seen would be a free option handed to you and a risk dumped on me: it starts from a time-and-materials analysis.	Data transformation and synchronisation between the systems Error handling and traceability of what actually went through Time and materials, not fixed price: here the scope is not predictable	On request	Let's discuss it in discovery
Setting up and looking after the production environmentServer, reverse proxy, certificates, backups and a repeatable release procedure that anyone on your team can run without being scared.I run my own infrastructure, not a client's yet. And for honesty: on my server the database backups are not active, by a deliberate choice of mine. On your environment they would be the first requirement, not an option.	Services, reverse proxy and certificates configured and documented A written release procedure, executable by someone else Automatic backups with a tested restore	On request	Let's discuss it in discovery
Phase zero of a legacy migrationBefore touching a dated system you measure what it actually does: an inventory of features, dependencies, data, risks. Without this phase, any quote is an invented number.I have never run a legacy migration: all of my work started from scratch. I can do this phase because it is analysis, but on a full migration I am not the safest choice you have, and I am telling you before you ask.	An inventory of the features actually in use A map of data and dependencies, with the breaking points A phased plan with an estimate for each phase	from €4,500per project	Let's discuss it in discovery
First modernisation phaseThe first block of features moved onto the new stack, with identical business logic, regression tests and a period where both systems run in parallel.No legacy migration on my record, and on a system that keeps your company running that counts. If you are looking for someone who has done it ten times, that is not me: judge me only after phase zero, once you have seen how I reason about your system.	Identical business logic, verified with regression tests Parallel running before switching the old system off Priced per phase, never a fixed total for the whole migration	from €28,000per project	Let's discuss it in discovery
Maintenance on a monthly fee after releaseAfter delivery somebody has to keep looking at it: security updates, fixes, small improvements, and a number to call when it breaks.I have maintained my own systems for years, but no client pays me to maintain theirs yet: it is a different thing, above all in response times, and it has to be said.	Security updates and fixes, with agreed response times Small improvements inside the hours of the chosen tier Three tiers — €390, €690 or €1,290 a month — chosen on criticality, not on budget	from €390per month	Let's discuss it in discovery

Technical SEO, Core Web Vitals and visibility to assistantsIndexing, structured data, perceived speed and how readable your site is to the assistants that now answer instead of the search engine.

Application security and automated pipeline checksA review of your application's security posture and the introduction of the checks that keep it over time, instead of a one-off assessment that ages in a month.No external client and no security certification. And an example from the right side of honesty: on my own system the AI service has neither its own token verification nor its own rate limit, both delegated to the gateway. It is a trade-off I know about and have written down — exactly the kind of thing you would come to me looking for.	from €1,900per project	Let's discuss it in discovery
Feasibility study for AI on your data, in your own houseIt answers one question only: is AI on your documents, without sending them out, feasible — with what hardware, what answer quality and what monthly cost.No external clients. The system I use to show you how it works is mine, but it is not on-prem for generation: semantic search runs on my server, the text is generated by OpenRouter (free plan). Prompts are not used to train the models; retention by the provider is not ruled out and data may leave the European Union. The on-prem measurements I can cite are those of 2026-08-03, when Ollama ran locally.	from €1,900per project	Let's discuss it in discovery
WCAG 2.1 AA accessibility checkA list of your application's non-conformities, in order of severity, with how each one is fixed. Not a tick box: a list of things to do.No accessibility audit has been commissioned to me by a third party and I hold no professional certification in the field: if you need a statement with legal value, that takes an accredited body, not me.	from €1,900per project	Let's discuss it in discovery
Review of a machine learning pipelineIf the model works beautifully in testing and badly in production, the problem is usually in the validation. Metrics, bias and information leaking from the data all get checked.The pipelines I can show you are five training project works on public datasets, not client commissions, and my own path on this topic is recent. I would rather tell you myself.	from €1,900per project	Let's discuss it in discovery
Architecture review with a reportA read of an existing or proposed architecture, closed by a written document: what risks you are running, what alternatives exist and why I recommend one of them.I can do it and I will show you on my own code, but I have not yet delivered it to an external client.

Recurring code review on your team's codeA periodic review with a written report: risks, the debt that is building up, what is worth fixing now.

Channel, partnerships and licences — Collaborations instead of commissions: agencies subcontracting, referrals, sponsored space, tools licensed out.
Item	What is included	Price	Action
Sponsored space on the site and newsletterSpace served directly by the site, with no third-party ad networks, inside technical content read by developers.I do not publish audience numbers because I have none that are verifiable to show you, and you would be buying an audience, not pages. Until I have those numbers the space is agreed case by case: it is not a price list, it is an honest negotiation.		On request	Let's discuss it in discovery
Affiliate mention inside the contentA product mentioned inside relevant technical content, always declared as affiliate. No products I would not use myself.As above, no audience numbers to show. And declaring the affiliation is not negotiable: it is a requirement, not an option.		On request	Let's discuss it in discovery
Development subcontracted for agenciesBackend, APIs, migrations, performance and in-house AI delivered on your behalf: the relationship with the end client stays yours, my name does not appear unless you want it to.No partner agency is active yet: the channel exists as infrastructure, not as a running relationship. The day rate is agreed on the type of work and on continuity.		On request	See the details
Referring a clientIf you refer somebody and that referral turns into an engagement, I pay you a share of the revenue for an agreed period. It is not a cost for you: it is income.The percentage and the duration are in the written terms of the programme. No referral has arrived yet and no fee has been paid.		On request	See the details
One of my tools under your brandCalculators, generators and validators that are already built, licensed under your brand and on your domain, embedded in your site if you want.I have never licensed it to anyone and a template contract does not exist yet: we write the first agreement together.	€390 a month for up to ten end clients €890 a month for up to fifty	from €390per month	Let's discuss it in discovery

Item	What is included	Price	Action
A technical talk at an eventA talk on one of the pillars — backend, frontend, career paths — built on real cases and on the trade-offs taken, not on generic slides.I have not given documented public talks yet, nor published recordings. For community meetups and conferences the fee is not the point: write to me and we will talk.		On request	Let's discuss it in discovery

Signature offers

These carry a full price rather than a threshold, because they are not compared against a generic alternative: each one rests on something you can open, run or re-measure yourself before paying me. The proof is written next to the item.

Signature offers

Twelve services resting on something you can verify before paying me: an identifier you resolve in your browser, a number you re-measure with one command, a system in production I show you.

Signature offers — Twelve services resting on something you can verify before paying me: an identifier you resolve in your browser, a number you re-measure with one command, a system in production I show you.
Item	What is included	Price	Action
Citable in thirty daysYour software and your data exist, but nobody can cite them. In a month they become a permanent record with an identifier that will still resolve ten years from now.The proof Ten identifiers already published and resolvable by anyone, with thirteen versions and three assets taken to 1.1.0 without breaking the existing links. Open one before deciding. Open it and checkThis method was born on my own system, not on a client's. I give you the system, the numbers and what you can verify yourself before paying me.	One published record per asset, with a stable identifier and a version identifier A validated citation file, licences consistent across code and data, a ready-to-paste citation string A structured, reproducible archive attached to the record, not just flat files A secret scan before the deposit, which is irreversible A versioning runbook of your own: the second version you do yourselves €1,400 for each additional asset in the same batch	€4,900per project	Let's discuss it in discovery
Your repository's operating systemThe senior left and the context left with them. I put back into the repository the information that today lives in somebody's head: conventions, traps, procedures, in a form a new human — or an agent — can follow alone.The proof The documentation layer was measured double-blind: three cold agents ran three procedures using only the repository documentation, and found on their own the three traps that had cost time in the past. This method was born on my own system, not on a client's. I give you the system, the numbers and what you can verify yourself before paying me.	A documentation layer inside the repository, not in a wiki nobody opens Runbooks for the recurring procedures, with the exact commands and the known traps A field test: someone who does not know the system runs the procedures and you measure where they get stuck Optional maintenance at €900 a month	€9,800per projectplus €900 per month	Let's discuss it in discovery
Hunting the false greenThe pipeline is green and production breaks anyway. I count how many tests you declare, how many actually run and how many are silently excluded, and I tell you where the suite is lying to you.The proof The «false green» case — a suite reporting zero executed tests while staying green — is documented and reproduced in two public archives with permanent identifiers. Open it and checkThis method was born on my own system, not on a client's. I give you the system, the numbers and what you can verify yourself before paying me.	A real count of declared, executed and excluded tests, per module A list of the silent exclusions and of who introduced them A pipeline check that fails the build if the number of executed tests drops €7,900 for a batch of up to three repositories	€4,400per project	Let's discuss it in discovery
Before the assistant answersMore and more people read an assistant's answer instead of opening your site. I make your content readable and citable by those assistants, and then measure whether you actually get cited.The proof Across 194 articles, from 741 structural findings down to zero, with a measurement anyone can re-run with a single command. The benchmark archive is public and has a permanent identifier. Open it and checkThis method was born on my own system, not on a client's. I give you the system, the numbers and what you can verify yourself before paying me.	Structural analysis of the content and correction of the problems found Entities and structured data consistent with what the page actually says Monthly monitoring at €1,100: the same measurement repeated with the same protocol, and therefore comparable over time	€7,400per projectplus €1,100 per month	Let's discuss it in discovery
Your data never leaves the buildingYou want AI on your documents but the data protection officer says no, and they are right. A pilot with the model running on your hardware: no document leaves your network.The proof Measured on 2026-08-03 on my server, when generation ran locally with Ollama: 5.7-7.2 seconds for a short answer, CPU only (three single measurements, not a benchmark). The site no longer works that way: retrieval stays local, but generation goes through OpenRouter, so I cannot show you the pilot in production. The public LocalMind project (AGPL licence, beta) is designed to use Ollama locally. This method was born on my own system, not on a client's. I give you the system, the numbers and what you can verify yourself before paying me.	Semantic search over your documents, with the model on your hardware A defined behaviour for when the model does not answer: no fallback to the outside Evaluation of answer quality, not just a demo that works Operations at €700 a month: model updates and monitoring	€16,500per projectplus €700 per month	Let's discuss it in discovery
One person, in productionYou have a system up and nobody to look after it, because the previous supplier disappeared. I take it over: I work out what it does, I document it and then I look after it.The proof I keep three microservices, a relational database, a cache, a reverse proxy and a local language model in production — alone, with six operational runbooks and the documented choice of having no automated release. One uncovered point I would rather tell you: I have not yet documented a complete restore exercise on my own system. On yours it would be the first thing we do, before signing any monitoring agreement.	Takeover: what the system does, what it depends on, what breaks it Operational runbooks, so that looking after it does not depend on me forever Monitoring at €1,600 a month, with agreed response times	€5,400per projectplus €1,600 per month	Let's discuss it in discovery
From the stage to the tillTill, receipt and pickup for a multi-stand event, with the thermal printer driven straight from the browser: no driver to install on every station, no third-party software.The proof The thermal printer is driven in its native protocol straight from the browser, two-dimensional barcodes included, with automatic reconnection: it was written for a real festival, not adapted from a generic product. The system has not been through a real event yet: the target date is in the future. Until that happens I cannot tell you it held up under a real load, and at an event the date does not move.	Ordering, payment, a receipt with a pickup code and a preparation display Printer driven from the browser, with no driver and no extra software A manual fallback procedure for when the venue's network gives up €21,000 for the annual licence with setup, if there is more than one event	€9,800per project	Let's discuss it in discovery
The academy you already haveNot two classroom days that get forgotten, but a ten-week internal path assembled from material already written and already paid for: modules, readings, labs on real tools.The proof The material already exists: 1,419 articles in two languages organised into about 167 series, 588 developer tools and 95 business tools. The production cost has already been paid, which is why the path costs less than building it from scratch. This method was born on my own system, not on a client's. I give you the system, the numbers and what you can verify yourself before paying me.	A ten-week path for a group of up to fifteen people Modules assembled from the existing catalogue, with labs wired to real tools Renewal at €4,200 a year: updated content and a new group	€13,500per projectplus €4,200 per year	Let's discuss it in discovery
Bilingual without lyingThe product is multilingual but half the translated strings do not exist, and nobody notices until a client sees English in the middle of Italian. You measure it, close the gap and put in a check that prevents it happening again.The proof This site keeps 26,213 translation units under a parity check that blocks the build, and has already been through the hard part: removing sixteen languages from production without losing the indexing. This method was born on my own system, not on a client's. I give you the system, the numbers and what you can verify yourself before paying me.	A real count of the missing strings, language by language A pipeline check that fails the build if parity breaks €2,400 for each language added or removed	€8,200per project	Let's discuss it in discovery
Research a reviewer cannot pick apartA study with a number of your own, built to survive someone trying to take it apart: method stated first, publishable data, limitations written by the author instead of found by the critic.The proof The method I apply always states two numbers: the one anyone can reproduce and the production one that cannot be verified from outside. That is the rule that makes a study hard to pick apart, and it is already applied to a public benchmark. This method was born on my own system, not on a client's. I give you the system, the numbers and what you can verify yourself before paying me.	Methodology stated before the results, and publishable raw data Limitations and non-verifiable numbers declared explicitly, not omitted Annual versioning at €3,500: the study stays alive instead of ageing	€19,000per projectplus €3,500 per year	Let's discuss it in discovery
From the script to the storeYou have a step your users do by hand in the browser. It becomes an extension published on the stores, with permissions cut to the minimum and the store listings already written.The proof Fifty-two extensions already packaged, with builds for the main browsers, screenshots, listings in two languages and the permission justification already written: the boring part is done. None of those extensions has been approved on a store yet: the packages are ready, the approvals are not. If your priority is «someone who has already been through review», today that is not me.	A working extension with the minimum permissions required Packages, icons, screenshots and store listings in two languages A written permission justification, which is the number one reason for rejection €2,600 for each additional store pack	€7,400per project	Let's discuss it in discovery
Performance with a receiptYou added advertising and the site got slow, but removing the advertising is not an option. Response times are recovered without giving up the revenue, and a check goes in that prevents the regression.The proof From 59 to 88 on mobile with four intervention patterns, the anti-pattern that had caused the problem and the measured effect of each one: the whole path is publicly deposited with a permanent identifier. Open it and checkThis method was born on my own system, not on a client's. I give you the system, the numbers and what you can verify yourself before paying me.	Measure before, intervene, measure after: the comparison, not a score The four intervention patterns that worked, applied to your case A pipeline check at €450 a month: the build fails if the timings get worse	€6,800per projectplus €450 per month	Let's discuss it in discovery

What makes the price of a project vary

These are the factors that move a quote the most. I put them in writing so you can form an idea before talking to me, not after.

Factors that make the price of a custom project vary, with their impact
Factor	Why it matters	Impact on price
Number of roles and permissions	An application with a single type of user and one with eight roles, each with its own permissions, are not the same job: every role adds screens, rules and cases to test.	High
Integrations with external systems	Every system you connect to (ERP, accounting, payments, couriers) brings its own documentation, its own limits and its own failures to handle.	High
Publishing on two stores	App Store and Google Play have separate accounts, signing, reviews and approval times: publishing on both is work in its own right, separate from development.	Medium
AI model and inference hardware	Running the model in-house means sizing the hardware, measuring latency and defining what must happen when the model does not answer.	High
Migration of existing data	Bringing in years of spreadsheets and old-software archives takes cleaning, reconciliation and spot checks: it is rarely a single import.	Medium
Hardware and on-site presence	When the system talks to printers, scanners or kiosks, and when the date cannot be moved, you need tests on real devices and someone physically there on the day: those are hours, and they have to be priced.	High
Level of accessibility required	WCAG AA conformance is my starting point. If a formal statement or a third-party audit is needed, checks and documentation are added.	Medium
Number of interface languages	Every extra language is a copy of the texts to keep aligned over time, not just a one-off translation.	Low
Training and support for the team	Handing over the code and handing it to a team that then maintains it alone are two different things: the second one adds sessions and documentation.	Low
