Top School

Joffrey Berrier is a pragmatic engineering leader and self-taught developer based in Paris with nearly a decade of hands-on experience and over two years in senior engineering leadership. He has built and scaled global tech teams (30+ engineers) across web, mobile and QA, led migrations from monolithic Rails apps to Rails APIs with Nuxt/Vue front-ends, and instituted CI/CD, testing, and analytics practices. A specialist in Vue/Nuxt and Ruby on Rails, he contributes to open-source UI components—improving date-picker UX and complex re-rendering behavior—and champions documentation, observability, and incident tooling in production. As a co-founder and head of engineering he blends startup creativity with execution, integrating acquired systems and building reusable acquisition tooling. Colleagues know him for turning operational emergencies into teachable improvements and for promoting a strong engineering culture through meetups and writings. He’s equally comfortable shipping front-end UX fixes as he is defining tech roadmaps and mentoring team leads.
