Senior🎓
Top SchoolGregoire Wulliamoz is a Technical Lead with 8 years of professional experience and a deep specialization in the .NET ecosystem and C#, focusing on robust web services and distributed systems. He has spent the past 6+ years architecting and delivering scalable EV charging platforms using modular monoliths, microservices, event-driven patterns and CQRS, and has production experience across AWS and Azure. Known for applying DDD, Event Storming and pragmatic testing practices, he also contributes to well-regarded modular-monolith DDD projects by improving architectural tests and API documentation. Gregoire blends hands-on backend engineering with platform-level concerns—CI/CD, containerization, message brokers, and high-availability deployments—while leading distributed teams across Switzerland, Ukraine and India. He pairs strong practical skills (Redis, RabbitMQ, PostgreSQL, Flyway, MassTransit) with occasional firmware and hardware POC work, reflecting a curiosity that spans cloud services to embedded systems. Based in Vaud, Switzerland, he’s driven by sustainable tech, particularly transforming EV charging systems into resilient, production-grade SaaS offerings.
