The person behind the projects

Physics mindset.
Engineering practice.

I’m a Physics graduate and MSc candidate at the University of Thessaly, focused on embedded IoT, wireless communications, software-defined radio and applied R&D.

I enjoy the entire engineering process: building hardware, writing firmware, measuring signals, diagnosing faults and turning data into useful systems.

Based in Thessaly, Greece · Open to engineering opportunities.
