In April 2024, I wrapped up a decade at Agora, where I’d been hands-on from day one, and set out to solve a new set of challenges. With years of B2B and solution design under my belt, I wanted to dive into a focused product that nails specific user pain points with an end-to-end solution.
At 19pine.ai, we’re blending the latest in AI—LLMs, TTS, STT, pre-training, fine-tuning, DPO, PPO, RLHF, and more—to tackle real problems: closing the information gap, handling customer service headaches, and leveling the playing field for individuals dealing with big organizations. Our beta has already helped U.S. users tackle these everyday issues head-on.
We’re hiring, so if AI is your thing and you’re ready to build something real, check out 19PINE.AI.

Partner & Tech VP

Feb 2014 – Apr 2024 · 10 yrs 2 mos · Santa Clara, California, United States · Hybrid

1. Launched SD-RTN™—an AI-powered global real-time audio/video network with 300+ nodes. Achieved <150ms latency and 99.999% packet reliability over public internet, setting new benchmarks in the industry. In other words, we made the public internet behave like a private superhighway.
2. Took SD-RTN™ from zero to an astonishing 1.1 trillion annual minutes—almost half of North America's total telecom volume—and seamlessly supported over 3 million concurrent users. All without breaking a sweat.
3. Led innovations in AI-driven real-time interactive systems that redefined the user experience and pushed the envelope on what’s possible.
4. Bonus round: Beyond engineering, I’ve played key roles as VP of Customer Success and Solution Architect. This has given me the unique ability to bridge deep tech expertise with customer needs and strategic business value. I thrive at the intersection of academic research, technical innovation, and commercial impact—ensuring solutions aren’t just smart, but also solve real problems and drive growth.

Right out of USTC CS, I joined Joyy when it was already making waves but not yet public. Built the web version of YY from the ground up and learned firsthand what it takes to grow with a tech company—real-time audio/video, reliable high-concurrency backends, and supporting millions of users smoothly. It was my intro to the startup world, tech innovation, and vitness of the journey from ambitious beginnings to a successful IPO. First job, big impact.
