PROFILE
Bartosz Rzepa
Worked on the software-mansion/smelter repository, focusing on enhancing media streaming reliability and performance evaluation. Addressed WHIP output stability by refining error handling and improving ICE candidate formatting, which reduced connection failures and increased system uptime. Standardized WebRTC codec registration for both audio and video, ensuring more robust and consistent connection setups. Later, developed a comprehensive benchmarking framework that enabled data-driven performance tuning, including MP4-to-YUV conversion and CSV-based reporting for clearer metrics. Leveraged Rust and C++ for system programming, integrating FFmpeg and networking concepts to streamline data processing and support reproducible performance analysis across the Smelter media pipeline.
