Worked on the defisaver/defisaver-positions-sdk repository to enhance CI/CD reliability by upgrading the GitHub Actions checkout action to version 6. Focused on improving pipeline performance and stability, the work involved refining YAML-based workflows and leveraging DevOps best practices to reduce flaky builds and accelerate pull request and release cycles. No user-facing features were introduced, but the upgrade resulted in faster CI pipeline startups and more consistent release readiness. By maintaining CI hygiene and updating core tooling, the changes supported increased engineering velocity and confidence in the SDK’s release process, demonstrating expertise in CI/CD, GitHub Actions, and YAML configuration.
