Who Am I

My passion for computer science was born between the desks of Istituto Tecnico Commerciale di Maglie, where I discovered the power of programming and the charm of creating digital solutions. From the start, I understood that computer science is not just code, but an extraordinary tool to transform ideas into reality.

During my higher studies in Sistemi Informativi Aziendali, I started intertwining computer science and economics, understanding how technology can be the engine of growth for any activity. This vision accompanied me to the Università degli Studi di Bari, where I earned a degree in Computer Science, deepening my technical skills and passion for software development.

Today I'm putting this experience at the service of businesses, professionals and startups by creating tailored digital solutions that automate processes, optimize resources and open up new opportunities for growth. Because true innovation begins when technology meets people's actual needs.

Technology Stack

Clean Architecture and Microservices

Spring Boot 3.4 (Java 21). Domain-Driven Design (DDD), Command Query Responsibility Segregation (CQRS) and Event Driven Systems with a four layer architecture decoupled from the application logic in the domain.

Front-end performance and Server-Side Rendering (SSR)

Angular 21 Server-Side Rendering (SSR), TypeScript in Strict Mode, Signals, and OnPush Change Detection for improved performance with Load Content Paint < 2.5 seconds and Web Content Accessibility Guidelines version 2.1 AAA compliance achieved.

Machine Learning and Data Science Engineering

PostgresSQL 16 optimizations, Redis Stack 7, Real-time Analytics Gateway (RAG) using RediSearch and Hierarchical Navigable Small World graph indexing, built on top of Fast API framework for high-performance APIs, utilizing the power of transformer-based models like sentence-transformers to generate dense vector embeddings.
