Worked on the google/heir repository to enhance codebase maintainability by focusing on code cleanup within C++ header files. The primary contribution involved removing a stale Copybara workaround comment from OpenFhePkeTemplates.h, which improved code readability and reduced the risk of confusion for future contributors. This targeted update streamlined the HEIR template includes, making the code paths clearer and onboarding more straightforward for new team members. Demonstrated skills in C/C++ and version control best practices, with an emphasis on maintaining project conventions. No bugs were addressed during this period, as the work centered exclusively on improving code hygiene and clarity.
