Developed a configurable Helm annotation feature for the SeldonIO/seldon-core repository, enabling per-environment customization of the controller deployment through Helm templates and values.yaml. Focused on YAML and Kubernetes, the work allowed teams to centrally manage deployment annotations, such as disabling Istio sidecar injection by default, directly within Helm charts. This approach reduced manual configuration, improved reproducibility, and streamlined governance across multiple Kubernetes clusters. By aligning deployment policies with Helm-based workflows, the solution enhanced operational safety and prepared the project for multi-tenant rollouts. The contribution demonstrated a practical application of Helm and Kubernetes skills to address deployment flexibility.
