A pragmatic Kubernetes and observability advocate, he builds helm charts, CI pipelines and benchmark platforms while using Grafana and Prometheus to keep performance visible and repeatable. Sébastien is an active open-source contributor, having fixed CPU and API issues in Apache NiFi and improved ClickHouse JDBC handling and Domoticz scripting—demonstrating both deep protocol knowledge and production-grade debugging. Comfortable spanning low-level networking protocols (SNMP, VoIP, custom protocols) to database plumbing (MySQL, ClickHouse, Redis), he pairs systems-level intuition with product-driven API and specification design. Based in the French Alps, he blends long-term product stewardship with a developer’s curiosity for practical performance tuning and integration challenges.
