What I'm looking for

I seek challenging roles building cross-platform player SDKs and embedded streaming systems, focusing on low-latency, secure, and high-performance video solutions.

I am a senior audio/video R&D engineer with ten years' experience in the security surveillance domain, skilled across the full stack from video capture and encoding to transmission, decoding, and rendering. I have deep hands-on expertise in cross-platform player SDK development for Windows, iOS, and Android, and in embedded devices such as IPCs and NVRs.

I have led and delivered projects that improved cloud playback latency, implemented TLS 1.3 0-RTT and IPv6 dual-stack support, and designed an intelligent TS caching and preloading system that reduced startup and seek times. I developed a high-performance Global Motion Estimation algorithm for PTZ rotation latency detection, authored a related invention patent, and contributed fixes and features to open-source components.

I am proficient in C/C++, Objective-C, shell scripting, Linux multi-threaded development, FFmpeg, ZLMediaKit, H.264/H.265, RTSP, GB28181, and network programming (TCP/IP, UDP, TLS, IPv6). I focus on measurable performance improvements, robust cross-platform integration, and secure, low-latency streaming solutions.
