Worked on the timescale/cloud-actions repository to enhance and stabilize continuous integration workflows over a two-month period. Initially addressed CI flakiness by removing arm64 from the multi-platform build strategy, consolidating builds to amd64 and reducing maintenance overhead. Later, reintroduced arm64 support by integrating a dedicated runner, restoring cross-architecture CI coverage and improving reliability for ARM64 workflows. Focused on maintaining compatibility with existing processes while simplifying configuration and ensuring auditability. Leveraged CI/CD best practices, GitHub Actions, and YAML to implement and document these changes, resulting in more robust, maintainable, and architecture-inclusive CI pipelines for the development team.
