I'm Leyen. I live in China, where I build the future.

I'm a full-stack developer who loves building things with code. I work across the stack—frontend to backend—using technologies like JavaScript, TypeScript, React, Node.js, and Python. I’m passionate about clean architecture, automation, and solving real problems efficiently.

Outside of development, I’m deeply interested in trading and financial markets. I enjoy applying programming and data analysis to explore market patterns, often blending code with strategy.

I believe in continuous learning, open sharing, and building in public. Here, you’ll find my projects, technical notes, and thoughts at the intersection of software and systems.
