Professional Summary

I’m Guillaume, a software engineer with 16 years of experience building and scaling high-performance systems- primarily in the financial industry. I’ve worked across the full stack, from low-latency infrastructure and in-house databases to risk analytics platforms and container orchestration at massive scale.

I enjoy solving complex engineering challenges, especially those involving performance, scale, and architecture. I’ve worked in both large global teams and startup-style environments, led development efforts, and collaborated directly with traders, product managers, and client teams.
