Worked on enhancing MP4 playback performance in the 5rahim/seanime repository by optimizing proxy settings to address streaming delays. Focused on backend development using Go, the solution involved disabling automatic response reading and compression within the proxy layer to stabilize streaming and reduce latency. This targeted feature improved user experience by lowering buffering risk and making resource usage more efficient during media playback. The approach demonstrated proficiency in API development and performance engineering, with incremental code changes that maintained clear traceability. The work emphasized maintainability and reliability, laying a foundation for future optimizations in proxy-based streaming workflows.
