Summary
🤩
Rockstar🎓
Top SchoolAntoni Zawodny is a Senior Software Engineer based in Warsaw with nine years of experience specializing in distributed systems, Kubernetes, and performance optimization. He has progressed through engineering roles at Google since 2020 and contributed directly to core Kubernetes projects—improving test infra, deployment scripts, logging, and performance tests—which demonstrates deep operational and architectural knowledge of a world-class open-source orchestration platform. Antoni combines hands-on DevOps and performance engineering (e.g., Prometheus-based measurements and OOM tracking) with system architecture work like kube-addon-manager changes and scalable Kubemark tuning. His background in both computer science and mathematics underpins a methodical, metrics-driven approach to reliability and efficiency. Notably, he has tackled subtle production concerns such as per-zone log exporting and JUnit report ordering, showing attention to both observability and correctness at scale.
