Who Am I

My passion for computer science was born among the desks of Istituto Tecnico Commerciale di Maglie, where I discovered the power of programming and the charm of creating digital solutions. From the very beginning, I understood that computer science wasn't just code, but an extraordinary tool for turning ideas into reality.

During my higher studies in Sistemi Informativi Aziendali, I began to intertwine computer science and economics, understanding how technology can be the driving force for growth in 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 my passion for software development.

Today I put this experience at the service of businesses, professionals and startups, creating tailored digital solutions that automate processes, optimize resources and open up new business opportunities. Because true innovation begins when technology meets the real needs of people.
