PROFILE

Morten Mjelva

Worked on Bazel-based build systems, focusing on dependency management and code coverage enhancements across grpc/bazel-central-registry and bazelbuild/rules_rust repositories. Delivered upgrades to grpc-java, first to version 1.68.1 and later to 1.71.0, by updating MODULE.bazel files and implementing module dependency overrides to ensure reliable downstream compatibility and build stability. Enhanced Rust toolchain coverage in rules_rust by integrating LLVM libraries into coverage runfiles, updating build file generation and the Rust compilation action to improve CI reliability. Utilized Starlark and Bazel extensively, demonstrating depth in build system automation, dependency resolution, and coverage infrastructure for large-scale open source projects.

Monthly summary for 2025-08: Focused on enhancing code coverage reliability for the bazelbuild/rules_rust repo and establishing LLVM library integration for coverage analysis. Implemented via a dedicated filegroup for LLVM libraries and a targeted update to the Rust compilation action to include these libraries when coverage is enabled. This change improves coverage accuracy, CI stability, and reduces coverage-related troubleshooting for Rust rules.
