Worked on the openstack-operator repository to deliver ACME and Let’s Encrypt certificate support for public routes, focusing on simplifying TLS secret handling in Kubernetes environments. Refactored the certificate validation logic in Go to require only tls.crt and tls.key, making ca.crt optional and enabling seamless integration with ACME providers. Adjusted backend logic to ensure the certificate chain is populated only when ca.crt is present, aligning with cert-manager’s embedding of the full chain in tls.crt. This feature reduced manual certificate management for public endpoints and improved security practices, demonstrating depth in backend development and Kubernetes operator workflows over the project period.
