Worked on backend reliability for the SpotiFLAC repository, focusing on download path handling across Unix and Linux environments. Addressed a critical bug where download paths were incorrectly prefixed with 'Unknown' by refining the logic to preserve empty strings for absolute paths, ensuring correct file placement regardless of platform. Emphasized robust path construction by explicitly handling edge cases and environment-specific semantics, which improved cross-platform consistency. No new user-facing features were introduced during this period, as the primary goal was to harden backend infrastructure. Utilized Go for backend development, applying strong attention to detail in code quality and platform compatibility.
