Worked on the tw93/Mole repository to enhance battery health percentage accuracy by preferring AppleSmartBattery data and ensuring correct integer conversion for cycle counts, resulting in more reliable user-facing battery metrics. Addressed a CodeQL alert by replacing unsafe float64-to-int casting with safer parsing methods, improving both safety and correctness in metric handling. Applied gofmt-based formatting and resolved variable alignment issues to increase code readability and maintainability within the battery metrics module. Utilized Go for backend development, focusing on data integrity and maintainable code structure. The work aligned with business goals of trustworthy metrics and reduced support costs through improved reliability.
