About

Senior C++ & WebRTC Engineer | Low-Latency Audio/Video, Streaming, Python & Full-Stack

Senior software architect and hands-on developer with 10+ years of experience building low-latency, high-concurrency audio/video and streaming systems.

My core expertise includes C++, WebRTC, Chromium/Blink/V8, RTP/RTMP/QUIC, FFmpeg, SFU media servers, congestion control, FEC, adaptive bitrate, multithreading, IPC, and performance optimization. I have designed production systems for remote driving, online education, real-time collaboration, live streaming, and cross-platform applications.

Previous projects achieved end-to-end latency at or below 80–100 ms in real 4G/5G environments and supported large-scale concurrent media distribution. I work across Windows, Linux, macOS, Android, iOS, embedded systems, and Docker-based deployments.

I also deliver complete products using Python/FastAPI, JavaScript, Vue 3, Go, microservices, and monitoring dashboards. My approach combines source-level protocol knowledge with pragmatic architecture, maintainable code, clear documentation, and reliable milestone delivery.

Available for architecture reviews, performance troubleshooting, focused module development, and end-to-end implementation of real-time communication and streaming products.

Work Terms

Available for part-time, milestone-based, and focused full-time engagements. I prefer clearly defined scope, deliverables, acceptance criteria, and milestones. Hourly or fixed-price contracts are both welcome, with payments handled through Guru SafePay.

I communicate through Guru messages and scheduled video calls. I am based in China Standard Time (GMT+08:00) and can arrange overlap with other time zones. Progress updates, technical documentation, and source-code handoff are included as agreed.
