Worked on the elixir-lang/elixir repository to enhance the Elixir compiler workflow by introducing granular recompilation control. Developed a new Mix task that enables selective recompilation of specific compilers, addressing the need for more flexible and reproducible build processes. Refactored the existing reenable logic to integrate with this new task, ensuring consistency throughout the build pipeline. Comprehensive tests were added to validate the new behavior across a range of recompilation scenarios, improving reliability for developers. This work leveraged expertise in Elixir, build tools, and compiler development, resulting in improved tooling and workflow for projects relying on the Elixir ecosystem.
