Summary
Romain Quellec is a senior full-stack engineer and technical leader with over a decade of experience taking products from 0 to 1, primarily in startup environments focused on climate and digital sustainability. He blends hands-on polyglot engineering (OCaml, Elixir, Haskell, Rust, Go, Python, TypeScript) with product-driven leadership—having served as CTO, lead developer, and manager while recruiting and scaling teams. Romain favors functional programming, TDD, modular monoliths and clean architecture, and has built data-intensive systems (Kafka, BigQuery, ElasticSearch, PostgreSQL) and web platforms that measure and reduce environmental impact. Comfortable shipping across front-end, back-end and data stacks, he also co-led product teams using Shape Up and iterated rapid MVPs for emission tracking and automated reporting. Based in Brittany, France, he combines startup pragmatism with a craft mindset and a track record of turning environmental mission into measurable business outcomes.
