What I'm looking for

I'm looking to contribute to open-source multimedia development involving device control, playback services, networking, and embedded platforms.

I develop production C software for embedded 5G signal-processing systems at Ericsson Nikola Tesla, translating algorithmic requirements into reliable functionality and verifying releases before delivery.

For my master’s thesis, I built a portable connected audio device on Embedded Linux and Raspberry Pi 4, combining Spotify Connect, local playback, battery support, Wi-Fi, and Bluetooth routing.

I coordinated librespot, mpv, and PipeWire with asynchronous workers and synchronized state, while implementing systemd, NetworkManager, caching, pagination, fault recovery, and Spotify REST/JSON APIs.

I’ve also built STM32 and ESP32 systems using FreeRTOS, MQTT, OpenCV, and embedded peripherals. I’m interested in open-source multimedia development across device control, playback services, networking, and embedded platforms.
