Summary
👤
Senior🎓
Top SchoolWilliam Claude is a hands-on senior engineering manager based in Lyon with 11 years of experience scaling distributed systems and leading high-performing teams across e-sports streaming and real-time matching domains. He began as a self-taught developer at 14 and has grown into a leader who combines deep backend engineering (Go, Kubernetes, AWS, event-driven architectures) with people-first management and hiring practice. At FACEIT he built and guided teams that delivered hundreds of thousands of hours watched and tens of thousands concurrent viewers, and at FREENOW he drove matching infrastructure, DDD-led refactors and a decentralised business rule engine that cut change cycles from weeks to minutes. He’s comfortable oscillating between coding and management, mentoring engineers, establishing processes, and fostering cross-team partnerships to meet strategic goals. Notably, he has a track record of re-architecting legacy monoliths into resilient microservices and recruiting senior engineers he previously worked with across companies.
