Worked on the Nextdoor/k8s-charts repository to deliver a feature enhancement for Kubernetes Helm charts, focusing on improving workload distribution across nodes. Developed support for custom labelSelector within topologySpreadConstraints, enabling cross-deployment pod spreading based on shared labels and removing the previous per-deployment limitation. The implementation, written in YAML and leveraging Helm and Kubernetes expertise, included comprehensive template tests covering both single and multiple constraint scenarios, as well as backward compatibility to preserve default behaviors. This change broadened deployment flexibility, allowing teams to optimize resource utilization and resilience for shared workloads, while maintaining stability across dependent chart families and applications.
