Worked on maintaining and improving the UCSD-E4E/smartfin-fw3 codebase, focusing on codebase hygiene rather than delivering new user-facing features. Addressed a repository integrity issue by removing a stray waterSensor.cpp file, ensuring that the codebase remained clean and free of redundant files. This effort enhanced build reliability and made the project more maintainable for future development. Utilized C++ and Git for source control and code management, emphasizing careful cleanup without introducing functional changes. The work prioritized reducing technical debt and smoothing the onboarding process for future contributors, laying a solid foundation for subsequent feature development and testing workflows.
