Jan Mensch

Jan Mensch builds databases, distributed systems, and cloud infrastructure as a software developer at ClickHouse. His work involves networking and keeping cloud services stable under heavy loads.

He tackles practical infrastructure challenges, like using eBPF for rate limiting at Layer 3 to prevent accidental stress tests from overwhelming reverse proxies.

When he isn’t working on databases, Jan spends his time windsurfing, cooking, and learning Spanish.
