Software Engineer · DevOps · SRE · Platform Engineer

An eternal enthusiast of technology, I started my career as a Java developer. I became interested in agility and Software Craftsmanship, and since I’ve always been drawn to system administration, I naturally transitioned into DevOps and SRE roles.

Engaged in both company and product vision, I enjoy working as part of a team, sharing knowledge, and automating anything that needs it, from CI/CD to operational tasks.

With a strong level of expertise and a broad culture spanning software development, software architecture, agile practices, and operational reliability, I act as a driver and facilitator for inter-team communication.

Finally, I hold strong values, especially regarding software quality and ecological sustainability. Without being dogmatic, I try to lead by example and guide teams toward what feels right.

My daily tools are zsh, tmux, vim, Intellij, git, docker, and various compilers/interpreters that help me speak binary more or less fluently.

I live in the Lille metropolitan area, work synchronously on the Paris time zone (mostly EMEA), and asynchronously with the rest of the world 😊.
