BACKGROUND
CTO at Good one, responsible for developing new features and maintaining the product alongside a talented team. After studying at 42 (Xavier Niel's school), I began my career as a backend engineer, gaining experience in tech, logistics, finance, and marketing startups.

I am passionate about building tools that simplify people's lives and creating interoperable systems to standardize APIs and data. Automating manual processes is especially rewarding for me.

I have always been fascinated by computers and technology, particularly devices with Wi-Fi. My curiosity drives me to explore both legacy and cutting-edge technologies, from barcode scanners on Windows Mobile to the latest robotic arms.
