Summary
👤
Senior🎓
Top SchoolLouis Sommer is a hybrid musician and web developer based in Paris with 8 years of experience building and maintaining Ruby on Rails applications while touring and producing at a professional level. Trained at Le Wagon, he has taught coding, acted as acting CTO for startups, and shipped production systems for clients like L'Oréal and the Web3 company RCRDSHP alongside notable Rails maintainers. An active open-source contributor, he has fixed authorization and file-handling issues in the popular avo admin gem and published his own project, abyme. He moves fluidly between roles—fullstack developer, educator, and technical lead—optimizing performance and rewriting codebases when teams need clarity. Unusually, his day-to-day blends high-stakes live performance (touring with artists such as Charlie Winston and La Roux) with long-running product maintenance. That combination gives him a pragmatic, user-focused engineering approach informed by real-world collaboration under pressure.
