Senior Product Manager · former Software Engineer
I build the platforms
other teams build on.
I’m Ziyue Zhang — call me JJ. I turn ambiguous, one-off needs into extensible systems — and I still ship the code behind them: end-to-end automation that retires brittle manual work, the data pipelines my team debugs on, and the delightful customer-facing frontends that keep users coming back.
About
Senior Product Manager and former software engineer with 6+ years building AI/data platforms, developer-facing APIs, and resilient infrastructure.
I’m known for systems-level thinking — creating extensible foundations other teams build on — and for translating fluidly between researchers, engineers, and executives. I’ve done this at Capital One, Hopper, Scale AI, and Microsoft: re-architecting infrastructure, shipping ML into production, and turning ambiguous, one-off needs into platforms other teams rely on.
I care about the craft of the build as much as the outcome — and I stay hands-on, using Claude daily to accelerate product, analytics, and engineering work.

So, what are you building?
I’m always glad to trade notes on product, platforms, and applied AI.
