Hire the Best GStreamer Specialists

I help companies build latency-sensitive audio systems and performance-critical native applications for embedded, desktop, and mobile platforms. My core expertise is turning complex low-level requirements into reliable and scalable architectures and implementations. Project Highlights: 1. Roc Streaming — co-founded and maintain an open-source real-time audio streaming ecosystem. 2. ViveSound audio engine — co-founded ViveSound and implemented commercial engine for OS-level audio processing injection. 3. Internet audio streaming — built a streaming daemon for embedded Linux with guaranteed 40 ms Internet latency, forward error correction and packet loss concealment. 4. Airborne audio synchronization — built acoustic-signature-based synchronization, aligning network playback to over-the-air audio within 1-2 ms. 5. Distributed playback sync — built multi-receiver network playback synchronization with sub-millisecond precision over high-jitter Internet connection.
