Worked on modernizing the Bazel build system for the EngFlow/example repository, focusing on upgrading rules_scala to version 7.0.0 and migrating dependency management to the Bazel Central Registry using Bzlmod. The approach involved removing custom extensions and patches in favor of standard Bazel tooling, enabling protobuf toolchain resolution, and configuring C++17 support for remote builds. Demonstrated compatibility with Scala 2.13.16 under the new setup and updated project documentation to reflect revised configuration options and usage. The work leveraged skills in Bazel, build system configuration, and Starlark, resulting in a streamlined and maintainable build process for the project.
