Anton Polshkov focused on improving CI reliability and security-testing workflows in the 0xPolygonHermez/cdk-erigon repository. He addressed a persistent issue with security tests by modifying the Docker container configuration to use the --network host option, enabling proper access to the Kurtosis-provided RPC URL during automated runs. This adjustment reduced test flakiness and allowed end-to-end security validation within the intended network environment. Anton’s work demonstrated practical expertise in CI/CD pipelines, Docker networking, and YAML-based configuration. While the scope was limited to a single bug fix, the solution addressed a nuanced integration challenge and contributed to more robust automated testing processes.
