Background


About

About

I am a Senior Software Engineer mainly focused on backend work at the moment. Coming from CentraleSupélec (Supélec course), high ranked French engineering school, and the student ISP association Supélec Rézo, I developed my already growing interest in computer science and system administration. I have enjoyed working on C++ and Python projects with complex functional and technical challenges. I have evolved to tech lead and more senior positions in different contexts but with similar challenging properties in the railway industry.I am a Senior Software Engineer mainly focused on backend work at the moment.

I have enjoyed working on C++ and Python projects with complex functional and technical challenges. I have evolved to tech lead and more senior positions in different contexts but with similar challenging properties in the railway industry. While I am living in the Rennes area in France I am also very open to remote and to move to other places, even in a different country, for the right opportunity. I am not limited by technology stack either as I can ramp up very quickly on your current stack. I am also passionate about self-hosting and decentralisation where I leverage my System Engineer and DevOps skills for a group of friends and I.
