Rockstar🎓
Top SchoolStéphane Copin is a Staff Software Engineer with over 11 years of experience building mobile and backend systems across France, the UK and New York, currently shaping product and platform at Compass. Trained at Centrale Lille and self-taught in C++ early on, he blends deep engineering fundamentals with pragmatic leadership—mentoring teams, defining company-wide best practices, and owning CI/CD and developer workflows. His background spans hands-on iOS and backend work, from leading mobile teams at Fueled to improving data sync and QA tooling in notable open-source projects like Sync and SwiftLint. Stéphane is as comfortable shipping robust tests and relationship-mapping logic as he is translating technical tradeoffs for non-technical stakeholders. He brings a proven track record of turning projects from concept to production and a habit of contributing practical fixes to the open-source ecosystem.
