Xiaowei Fan developed and delivered a Helm chart for the OVH cert-manager webhook in the NethermindEth/helm-charts repository, enabling automated certificate provisioning via ACME DNS01 challenges with OVH DNS. The work focused on streamlining TLS certificate workflows in Kubernetes environments, reducing manual intervention and improving deployment reliability. Xiaowei applied DevOps practices and YAML expertise to implement security hardening through seccompProfile configurations and standardized versioning across multiple charts. This approach enhanced the security posture and maintainability of the chart suite. The project demonstrated disciplined chart maintenance, commit traceability, and a focus on operational excellence within Kubernetes and Helm-based infrastructure.
