02 About Me

I'm Zo, an independent fullstack developer.

From quantitative trading bots to GIS surveillance platforms, from microservice game systems to cross-platform desktop apps — I love solving real problems with technology. My stack spans Python, Node.js, Java, and TypeScript, delivering end-to-end from architecture design to cloud deployment.

Currently freelancing, serving clients across fintech, public health, agriculture education, and gaming entertainment.
