Worked on the tianocore/edk2 repository to expand the SpellCheck dictionary, focusing on reducing false positives during code and documentation reviews. The approach involved managing and updating YAML-based dictionary files, specifically adding new terms to ExtendWords within ArmPlatformPkg. This targeted enhancement improved spell checking accuracy, enabling developers to identify genuine issues more efficiently and accelerating platform bring-up. The work required close collaboration across teams, as evidenced by broad code review participation, and demonstrated attention to code quality and maintainability. Skills applied included dictionary management and spell checking, laying the foundation for scalable future improvements to the EDK2 spell-check system.
