Summary
🤩
Rockstar🎓
Top SchoolGuillaume Grossetie is a founder and seasoned software architect with 14 years of experience building scalable, production-grade systems and developer tools from Lyon, France. He has led large platform engineering efforts—designing a Kafka/Elasticsearch-based monitoring pipeline at Enedis that processes tens of thousands of metrics per second—while also founding and growing Yuzu tech. Hands-on across the stack, Guillaume contributes to notable open-source projects (Mill, Asciidoctor, PlantUML, Kroki and GitLab) where he’s added template and router compilation, improved JVM bindings, extended diagram rendering and modernized build/release flows. His strengths span distributed data pipelines, automation (Ansible, Jenkins), Java/Node ecosystems and front-end pagination/print tooling, demonstrating a rare mix of backend, devops and UI experience. He often focuses on practical interoperability—bridging tools like Play!, Asciidoctor and Kroki—and on improving developer workflows and build performance. Curious and pragmatic, he combines architect-level design with deep implementation skills, frequently contributing cross-language fixes and integrations that quietly improve widely used tooling.
