Rockstar🎓
Top SchoolMaciej Kwiek is a software engineer with 11 years of experience specialising in cloud-native back-end and DevOps engineering, currently at Isovalent in Greater Poland. He has a strong track record in Kubernetes ecosystem projects, contributing to Helm, kops, and Cilium—work that ranges from stabilising release operations and experimental architecture to integrating Cilium as a CNI with TLS and version validation. Maciej blends systems-level networking knowledge (eBPF, L7 proxies, connection tracking) with practical API and tooling improvements, having also extended Jira client libraries and upstream Kubernetes components. His career spans startup and product-focused roles where he moved between research, design and hands-on implementation, and he’s comfortable across CI/CD, cluster plumbing and API design. An interesting non-obvious detail: he’s implemented release locking and experimental Rudder extensions in Helm, highlighting a focus on safe concurrent operations and extensible orchestration. He holds a B.S. in Computer Science from Poznań University of Technology and remains active in open-source infrastructure work.
