PROFILE
Albert Stefanov
Over three months, Alex Stefanov enhanced the FOSDEM/video firmware by delivering six features and resolving two bugs, focusing on audio processing and embedded systems reliability. He modularized the audio engine and display subsystems, introduced persistent channel state using EEPROM, and enabled default USB audio routing to streamline device setup. His work included refactoring code for maintainability, exposing mixer state via the OSC protocol, and automating configuration with Python scripting. Using C, C++, and CMake, Alex addressed both architectural and usability challenges, resulting in more robust audio mixing, improved state retention, and reduced support overhead for the FOSDEM/video repository.
