Worked on the bazelbuild/bazel repository to address reliability issues in test coverage collection during flaky test retries. Focused on improving the split coverage process by ensuring that coverage is skipped on failed attempts and that stale metadata is cleared after sandbox cleanup. This Java-based solution targeted a critical incompatibility that previously caused FileNotFoundException errors, thereby stabilizing continuous integration workflows. Leveraged expertise in build systems, software testing, and test automation to enhance the accuracy of coverage reporting and reduce pipeline failures. The work resulted in more reliable CI feedback and minimized disruptions caused by flaky tests, contributing to smoother development cycles.
