Worked on improving CI stability and compatibility for the elastic/beats repository, focusing on resolving failures related to Synthetics tests. Addressed a key bug by upgrading the Node.js version used in continuous integration workflows to the active LTS release, which eliminated incompatibility issues introduced by recent changes. Validated the updated build system to ensure more reliable and consistent test execution, reducing the occurrence of flaky runs and accelerating feedback cycles for the team. Leveraged expertise in CI/CD processes and build systems, primarily working with YAML to define and manage workflow configurations, resulting in a more robust and maintainable CI environment.
