Worked on the UWOrbital/OBC-firmware repository to enhance data integrity and reliability in embedded systems. Focused on backend development using Python, SQLAlchemy, and SQLModel, addressing a critical bug related to MainCommand data validation. Implemented robust validation logic to ensure command parameters consistently matched expected formats, reducing the risk of malformed commands reaching hardware. Developed comprehensive unit tests to cover scenarios with missing or mismatched parameters, improving test coverage and maintainability. The work emphasized careful attention to data validation and thorough testing practices, resulting in a more reliable firmware codebase and streamlined future development for the MainCommand component.
