Software Architect · Go & Distributed Systems · 20+ Years Experience · Paris, France
I build and run event-driven, high-volume data platforms in Go, and I carry the pager for what I design. My speciality is modernising systems under live traffic — taking legacy services off the critical path and rebuilding them in Go on hybrid multicloud Kubernetes while holding low-millisecond p99. I fix the upstream libraries production depends on rather than working around them.

174 merged pull requests to projects maintained by others.
Redpanda Connect — 49 merged PRs: new and extended connectors (Elasticsearch v9, SQLite, Couchbase scopes, kafka_franz topic control, cache components), remediation of ~9 Go security advisories, and codebase-wide quality work including linter enablement and the mapstructure migration.
