Alan Kutniewski is a Senior Software Engineer based in Warsaw with six years of hands-on experience building cloud-native, back-end systems. At Google he contributes to high-impact open source projects like Cilium and the GCE ingress controller, focusing on eBPF-based networking, security, and EndpointSlice support for Kubernetes. His work shows a strong practical grasp of distributed systems: optimizing memory usage, refactoring controllers for full reconciliation, handling update conflicts, and migrating identity garbage collection. Alan pairs pragmatic engineering with deep platform knowledge, making reliability and compatibility improvements that benefit large-scale Kubernetes deployments. A detail often overlooked: his commits reflect both bug fixes and architectural changes, indicating he moves fluidly between short-term stabilization and longer-term code health.
