About

I started in 2011, writing Java for a city-life community with a million daily actives. Then came billing systems at Anjuke — over a million transactions a day, where I first learned that production verifies every assumption your code quietly makes.

The next decade ran along the architecture-and-management track: architect roles at a securities firm and a fintech company — splitting monoliths, building service platforms; then engineering director at Macalline's Hongxing Cloud, leading a team of 70+ at its peak and delivering 30+ B2B projects over five years, including systems like a gateway handling 500k+ TPS a day. Half of what those years taught me was technology; the other half was people — getting a group to ship reliably is much harder than writing good code.

In 2023 I left the platform to co-found a startup as its technical partner, and started building indie products on the side. My roles keep getting "smaller": from managing 70 people to managing myself, from reviewing code to writing it every day. Verdict: the latter is more fun. The full feedback loop of a product — people using it, complaining about it, paying for it — is something a big organization can't give you.

One more thing: ten years into my career I went back to university for a second bachelor's degree, in Chinese literature. The line on the homepage — "I ship code, and write it down" — isn't a throwaway.
