PROFILE

Lars Sjöström

Lars contributed backend features to derailed/k9s and envoyproxy/gateway, focusing on reliability and configuration management. For derailed/k9s, he implemented WebSocket-based port forwarding in Go, mirroring kubectl’s approach and providing a fallback to SPDY, with rollout controlled by environment variables to support gradual adoption in restricted networks. In envoyproxy/gateway, Lars improved deployment stability by disabling outlier detection by default, ensuring passive health checks are only enabled when explicitly configured. This work involved updates to Go code and YAML test files, reducing false-positive health signals and supporting more reliable production monitoring. His contributions demonstrated depth in Go, Kubernetes, and networking.
