Worked on modularml/mojo to streamline the build system for WebAssembly and Emscripten targets by removing wasm-specific configurations from the C++ toolchain. This approach reduced complexity in build targets and flags, minimizing the risk of misconfigurations and improving overall maintainability. Leveraging expertise in Bazel and C++ toolchain configuration, the changes enhanced build reliability and made onboarding easier for developers working with wasm or Emscripten. The update also aligned with ongoing dependency hygiene efforts, particularly regarding MOTR dependencies, and laid the foundation for more reliable cross-target builds and faster iteration cycles within the modularml/mojo repository’s build workflows.
