PROFILE
Albert Stefanov
Worked on the FOSDEM/video repository to deliver audio firmware and embedded system enhancements over three months, focusing on reliability, maintainability, and usability. Developed modular audio processing features in C and C++, including a flexible audio engine, persistent channel state using EEPROM, and default USB audio routing to streamline device setup. Improved system observability by exposing mixer state via the OSC protocol and stabilized the display subsystem through code refactoring. Addressed bugs in mute logic and OSC messaging, while strengthening build processes with CMake and scripting. The work resulted in robust audio behavior, easier configuration, and reduced support overhead for end users.
