Quentin Valmori is a seasoned technology leader and hands-on CTO with 11 years of experience building product-focused teams and shipping cross-platform applications from France. He has repeatedly combined front-end expertise in React and React Native with back-end work in Node.js, Go and Python while championing testing, performance and developer ergonomics across organizations like Cozy Cloud and Twake.AI. As a founder and longtime technical lead he’s hired and mentored engineering teams, introduced robust CI/e2e practices, and helped define company strategy and product roadmaps. An active open-source contributor, he’s improved React Native Material components and fixed multi-platform bugs in Cozy’s stack—practical work that reflects his UI-first sensibility and attention to edge-case UX. Notably, he built client-side tooling (a React Query–like solution) and fostered calmer, experimental engineering cultures that boost velocity and ownership.
