yytyyfA 2026 master's grad from Peking University and an indie developer. I taught myself UI design at a startup, then taught myself to code and built Feisou. I worked on AI products at Moonshot and Feishu, and now I build my own things full time. On the side I draw a rabbit called Tuji, and once sold prints at a market stall with my mum.
Went all in on AI coding, building Swob, KeyKeeper and the rest in parallel with a crew of agents. Everything is on the home page.
Took the AI Productivity Report from zero to launch, coordinating design, data, backend, frontend and mobile — 12+ functions. Shipped on schedule and converted to full time.
Produced the featured cases on the Researcher home page and built the good-case pipeline and agentic dataset behind it.
A search engine for public Feishu docs. Top three at the "Road to AGI" demo day; the rebuilt web version reached 5,000+ users in its first month.
Taught myself UI design from scratch and delivered high-fidelity designs for two B2B product lines in two months, including the brand system still in use today.
