Worked on the cosmos/evm repository to enhance continuous integration performance and reliability by upgrading GitHub Actions runners to larger depo-ubuntu-22.04-4 environments. Focused on stabilizing and accelerating feedback loops for unit, script, and fuzz test suites, the work reduced test flakiness and improved throughput across CI workflows. Leveraged CI/CD best practices and YAML configuration to standardize the runner environment, resulting in faster and more consistent test execution. Documented configuration changes and their impact on test timings to support future optimization efforts. This approach enabled more efficient pull request and release cycles by ensuring reliable and repeatable CI processes.
