Available to hire
I’m Olivier Colonna, a Staff Platform / Full-Stack TypeScript Engineer based in France with 15+ years of building production web products across frontend, backend, platform, infrastructure, payments, and developer experience. I work closely with users and product teams to ship pragmatic architecture decisions and stay accountable for outcomes after launch.
I bring long-term product ownership, startup speed, and hands-on IC leadership. I’ve led architecture, TypeScript, React/Next.js, APIs, performance, auth, payments, deployment, and code review in environments like Lucid / Cint and Drivetribe, while remaining deeply involved in implementation. I prefer simple, explicit systems that are easy to reason about, test, and evolve, and I stay focused on user value and product outcomes.
