Jan 1, 2026January 2026 monthly summary for goharbor/harbor: Delivered OCI repository type support in the JFrog registry adapter, enabling OCI-based replication and broader container image format coverage; enhanced proxy cache referrer API with a UI toggle and upstream proxying, and updated terminology across language files from 'pull-through cache' to 'proxy cache'; and performed a rollback to revert the proxy cache referrer UI changes and upstream proxying due to issues to preserve stability. The work included tests updates for OCI paths and UI-related changes, demonstrating Go backend work, testing, and frontend/UI integration. Business value: expanded compatibility, clearer UX, and safer rollout with rollback capability.

Dec 1, 2025December 2025: Three core deliverables across goharbor/harbor focused on upgrade control, CI/CD reliability, and enhanced search. Implemented HARBOR_ADMIN for upgrade scripts, fixed CI/CD log uploads to happen regardless of job outcome, and introduced fuzzy search for users and groups with DB-query optimization. These changes reduce manual intervention during upgrades, improve post-run observability and debugging, and deliver faster, more accurate admin search results across tenants.

Sep 1, 20252025-09 Monthly Summary for goharbor/harbor: Delivered reliability and scalability enhancements through targeted fixes and a new throughput control feature in the proxy cache layer. Key improvements include the introduction of max_upstream_conn to cap concurrent upstream connections per proxy_cache project, with accompanying API/model updates and Redis-based enforcement to optimize resource utilization. Major bugs fixed include CI webhook validation in the GitHub Actions workflow by removing the port from the Harbor IP to ensure correct IP comparisons, and a test-suite cleanup removing deprecated GCR replication tests and P2P Preheat By Event test steps to restore CI stability. These efforts reduced CI failures, eliminated flaky tests, and improved upstream cache efficiency. The work demonstrates strong skills in CI/CD, API design, Redis-based state management, and test hygiene, delivering measurable business value through more reliable deployments, lower compute costs, and better resource planning.
