Over a decade ago I taught myself to code through Google and Stack Overflow, landed my first engineering job in Wuhan, and eventually grew into a team lead at Geetest. From there I moved to Shanghai and Shenzhen, working alongside sharp people across different domains and industries.

After the pandemic, I moved to Japan — another new chapter, both professionally and personally. Outside of code, I like good coffee, good food, new places to visit, and things that are actually worth watching.

At Geetest, I grew from the sole web developer into the lead of a 10-person engineering team. That period shaped how I think about ownership: not just writing features, but building systems, mentoring teammates, and keeping the product moving as the company scaled.

Later, I joined BITO Robotics, working with Carnegie Mellon researchers on autonomous forklift navigation. At Shucheng AI, I collaborated with a founding team from Stanford and Michigan on warehouse design automation, turning research-heavy ideas into usable web-based systems.

Most recently, I've been building sky-finance — a production-grade financial intelligence platform that ties together hybrid RAG retrieval, multi-provider LLM routing, and LLM-as-judge evaluation. It's where my full-stack instincts meet the AI engineering systems I actually enjoy building.

I do my best work in high-ownership environments where product direction, architecture, and shipping speed are closely connected. I like taking ambiguous problems end-to-end: defining the system boundary, choosing pragmatic tools, building the first version, and hardening it until real users can depend on it.

Outside of work, I'm a dedicated explorer of the quieter side of Tokyo. On many weekends, you'll find me at Ueno Park, and my favorite place in all of Japan is Hitachi Seaside Park — especially when the nemophila fields turn the hillside blue.
