Summary
🤩
Rockstar🎓
Top SchoolGuillaume Faas is a Senior .NET Developer Advocate with over a decade of hands-on experience helping teams build reliable, maintainable software and shipping developer-facing content. Based in France, he blends technical coaching and leadership — from cloud-native .NET architectures and TDD/ATDD to Clean Architecture, DDD and CI practices — with public speaking, training and community organization. At Vonage he evangelizes .NET practices while maintaining active roles as host/organizer for Software Craft Luxembourg and as a creator for the Xtrem TDD open-source workshops. He has led and coached large teams (up to 13 devs) on enterprise modernization, developer experience and delivery sustainability across finance and regulatory domains. Known for pragmatic craftsmanship, he often pairs theory (mutation testing, property-based testing, railway programming) with ready-to-run workshops and katas to accelerate learning. Beyond coding, he quietly drives internal communities and blueprints that help organizations adopt better engineering habits.
