My digital corner. Science, code, thoughts.

About

I am a Software Engineer and student at Epitech Barcelona.

My current focus is Systems Programming. I architect software that demands performance and a rigorous interface between computational logic and the physical world. This specialization is built upon a professional foundation of shipping production systems and a track record of technical reliability.
