PROFILE

Matt Mackay

Matt worked on build system improvements for the aspect-build/rules_py and bazelbuild/rules_rust repositories, focusing on CI/CD automation, toolchain modernization, and cross-version compatibility. He enhanced CI workflows to provide faster feedback on pull requests, upgraded the Rust toolchain and dependencies for improved stability, and introduced a binary_name attribute to the rust_binary rule, allowing customizable output filenames. Using Bazel, Rust, and Python, Matt addressed a bug by decoupling binary names from target names and restored CI stability by reverting type hints for legacy Python support. His work reduced build failures, improved artifact control, and streamlined development across multiple environments and repositories.
