01 // About me

Curiosity turned into solutions

It all started with a simple question: how does this work? Curiosity about what happens behind every product led me to programming. Since then, I have turned continuous learning into tools for building new things.

That drive has become real products: management systems that organize teamwork, tools that automate manual processes, and applications developed end to end, from data modeling to cloud deployment.

I hold a degree in Computer Science Engineering from the University of Informatics Sciences (UCI). I aim to create clear, maintainable, and useful software by combining sound technical decisions with a natural user experience.
