About

Engineer who thinks like a founder.

I'm a Computer Science student at the National and Kapodistrian University of Athens with a deep drive to build things that matter. My journey started young — web development, system administration, security — always learning by doing.

Right now I'm all-in on entrepreneurship. As the CTO of a stealth startup, I'm single-handedly architecting and building the entire product from scratch. Every technical decision, every line of code, every infrastructure choice — that's me.

I also give back through teaching. I work alongside the lab instructor in university workshops — answering student questions, debugging exercises with them, and turning theory into practice. Building, shipping, mentoring — that's the loop.
