What drives me: understanding What pushes me: doing better

Final-year software engineer specializing in embedded and critical systems architecture. Technical rigor is not just a buzzword for me — it comes from hard-earned discipline: CPGE prep school and calisthenics training both taught me that lasting results require daily consistency: managing sleep, time, and priorities without compromise.

I value teamwork because I have seen first-hand what happens when it breaks down. During a study project for Fortil, poor team dynamics led to friction that slowed the whole project. What I took from that: quality work only happens in an environment where everyone is respected and heard. Since then, I make a point of staying organized, respecting others' deadlines, and anticipating the team's needs before my own.

In parallel, I take on entrepreneurial projects — for myself, my network, and future clients. This led to my first collaboration with an American client, allowing me to confront my engineering knowledge with the reality of an actual business order. It is through these end-to-end projects that I learn the most.

My time in Tokyo — as the only French member of a Japanese research team, with no safety net — taught me above all to be resourceful: find a solution, not necessarily the perfect one, but one that moves things forward. I apply that same logic to technical decisions: I build my own arguments, document my reasoning, and own my choices.
