STORY

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.

THE WORK THREAD

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 the University of Michigan on warehouse design automation, turning research-heavy ideas into usable web-based systems.

Now in Japan, I'm continuing the same thread: building practical software across new markets, learning from each context, and using engineering as a way to turn ambiguity into something real.

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.

HOW I WORK

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.

TOKYO // LIFE

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.

>> GamesDivinity: Original Sin 2 is my favorite PC game of all time, and Fire Emblem: Three Houses is the game I have played the most on the Nintendo Switch. RPGs with strong characters and meaningful choices are what I keep coming back to.
>> TVI like Breaking Bad and Better Call Saul, and I am a big fan of Vince Gilligan's work. Dramas with detailed storytelling and well-written characters are what I enjoy most.
>> Manga & AnimeI like Dragon Ball and One Piece, and I have been watching Frieren: Beyond Journey's End recently. Manga with memorable characters and a strong sense of adventure is what draws me in.
>> FoodI love beef, especially Wagyu, and I enjoy looking for good steak and other beef dishes during holidays. I also like trying delicious food in general whenever I travel or have time off.

Started in Wuhan. Landed in Tokyo. Next stop — still exploring.
