About Me

A computer scientist shaped by two countries, driven by a passion for software that matters.

I'm pursuing my Master's in Software and Systems at Universidad Politécnica de Madrid, after completing my BSc in Computer Science at the University of Western Macedonia in Greece and an Erasmus+ exchange at UCLM in Spain.

With over 30 certifications and a growing body of real projects from iOS apps to machine learning pipelines, I combine academic rigor with a strong hands-on approach. I believe the best software is invisible: it just works, beautifully.
