I’m Ethan Yanjia Li, a software engineer and technology enthusiast. My specialties are around computer vision and augmented reality. I’m also very excited about entrepreneurship that improves human life with AR / AI technology.

This site is very opinionated, so please don’t take it too serious. Writing these posts helps me to consolidate my knowledge, and I hope it can inspire you from a different perspective too. Meanwhile, it’s a great pleasure to hear your thoughts as well.

There’re three major sections of this site: “Technology” is for discussions in IT development; “Opinion” is my personal notes on various social and economic topics. “Books” just shows my Goodreads history.
