Over a two-month period, contributed to security and reliability improvements in the angular/angular and google/osv-scalibr repositories. In angular/angular, enhanced CI workflow security by refactoring the Benchmark-Compare GitHub Action to enforce non-shell execution and proper argument quoting, reducing OS command injection risks and improving automation reproducibility. For google/osv-scalibr, delivered targeted bug fixes and features to improve vulnerability detection, including accurate Swift package identification and expanded ecosystem mapping for AlmaLinux, Wolfi, and Chainguard. Leveraged Go, TypeScript, and Docker to implement integration tests and maintain code quality, focusing on backend development, containerization, and DevOps best practices throughout the work.
