/ About
Hey, I'm sleep9ull.
AI product manager based in Shanghai. I take product and engineering together, and I ship the product myself.
Data is a stance, not a report. See clearly, then move. AI and vibe coding accelerate the cycle; judgment stays human.
At work: AI data PM on Viba, the company’s AI Styling Agent. Data-first exploration of the boundaries, and I lead commercialization inside the product.
On my own: Sudoku Sama, an iOS puzzle—a long think and one critical choice to finish the daily puzzle. On the App Store.
Still learning. Karpathy’s LLM walkthrough got me into AI and laid the foundation. Heavy Grok Bot, for work and life. Codex is my daily work tool. I prefer 6 Astra over 6.1 Sol.
I studied architecture and worked as an architect for a few years; now I build product. That still helps me solve the whole problem, and it helps a little with taste. A bit of everything—with AI I aim for about an 80 on each. Together, that’s strong.
