Rockstar🎓
Top SchoolValentin Cocaud is a seasoned fullstack developer with 11 years of experience and nearly 9 years focused on designing and maintaining scalable GraphQL, Node.js and TypeScript architectures for SaaS, startups and software vendors. As a recognized maintainer of major open-source GraphQL projects (GraphQL Yoga, Envelop, GraphQL Mesh, Hive Gateway) he combines deep performance and extensibility expertise with day-to-day product delivery and developer experience improvements. He has a track record of modernizing legacy stacks, drastically speeding up build and CI times, and implementing robust backend features—from low-latency streaming systems to secure PGP file flows. Equally comfortable mentoring teams and shipping production-ready code, Valentin blends systems thinking with pragmatic engineering to improve reliability, observability and long-term maintainability. Based in Nantes, he also contributes lower-level work in Go (e.g., fixes in pion/mediadevices) showing a rare cross-domain skillset spanning web, realtime and systems-level engineering.
