About Matthieu

Backend & full-stack software engineer, I design and develop robust applications with Golang and Angular. Comfortable with the entire project lifecycle: microservices architecture, APIs, DevOps, CI/CD; I also enjoy being involved on the product side: user interviews, UX, strategic choices.
I appreciate environments where technology has a concrete impact on end-users.
Curious and autonomous, I am looking for assignments where I can contribute to a real product, not just execute tickets.
