Worked on the elastic/monaco-esql repository to establish a robust CI/CD pipeline using Buildkite, enabling automated builds and tests for the Monaco-ESQL project. Focused on improving delivery speed and test reliability by updating the Playwright dependency to version 1.55.0, ensuring access to the latest testing features and greater stability. Merged a renovate pull request to align Playwright versions across the monorepo, reducing maintenance overhead and dependency drift. The work leveraged skills in CI/CD, DevOps, and TypeScript, with Bash and YAML used for scripting and configuration. This effort laid the groundwork for more efficient and reliable development workflows.
