Rockstar🎓
Top SchoolArtur Shellunts is a senior software engineer based in Göppingen, Germany, with 7+ years focused on video codecs, real-time communication and C++ system engineering. He has driven production improvements at TeamViewer (VP9 SVC for large meetings) and contributed to LiveKit and the widely used pion/webrtc and flutter-webrtc open-source projects, implementing H.264 parsing, per-track telemetry and cross-platform WebRTC fixes. Comfortable across backend, mobile and test automation, he combines low-level codec expertise with pragmatic CI/CD and testing practices introduced at scale. Artur’s background includes hardware-accelerated decoder work at Intel and practical experience shipping features from prototype iOS apps to SFU servers, reflecting a strong end-to-end view of media systems. A pragmatic TDD advocate and mentor, he often pairs deep protocol knowledge (RTP/STUN/SDP) with automation to raise reliability of real-time media stacks.
