About

Building things
that matter

I'm a Computer Scientist & Engineer with an Integrated Master's degree in Computer Science & Engineering from the University of Ioannina.

I have worked across research and product environments, from smart energy optimization projects to production SaaS platforms, contributing to frontend features, backend services, and database workflows.

I enjoy solving complex technical problems with practical solutions, and outside of work I spend my time playing guitar and watching cinema.
