Worked on the vmware/govmomi repository to deliver a feature enhancing certificate management by allowing flexible CSR duration input. Implemented logic to accept the duration as a string, parse it into an integer, and ensure accurate certificate expiration calculations, addressing potential misconfigurations and supporting automation in deployment pipelines. Focused on maintaining API compatibility and improving validation and error messaging around CSR durations, aligning with security and compliance requirements. Utilized Go and Bash for backend and API development, with an emphasis on robust testing. The work demonstrated attention to detail in security best practices and readiness for automated certificate provisioning workflows.
