The Journey

From Energy Engineer to Software Engineer

I spent 5 years as an energy engineer at ENGIE in the south of France, then 6 years in financial markets as a certified Financial Investment Advisor and systematic trader.

Two years ago, I pivoted into software engineering. Since then, I've shipped 13 production applications and 2 Chrome extensions — SaaS, e-commerce, AI agents, and browser tools — all as a solo developer.

In 2024, I completed an Ironman triathlon after learning to swim freestyle in just 3 months. I bring that same intensity to everything I build.
