About Sébastien

Self-taught since I was 14, after a career as an Art Director, I returned to coding and have been living from it since 2014. From websites to web apps. Complexity does not scare me. Always passionate about web technologies, I now produce multi-process, asynchronous information systems with ultra-fast communication layers, robotics systems, and embedded software. To gain productivity, I always keep an eye on the evolution of testing, CI/CD pipelines, and infrastructure as code. I use AI and especially Claude Code since sonnet 3.5
