I live in Longmont, CO USA. I’m a programmer for a company. My most tasks are front-end developments utilizing Angular, sometime back-end Java Spring Boot, the ratio is 90% and 10%. On my private time, I’m building a web application with Angular, Go and MongoDB stack. I like learn new technology and make something physically and digitally, especially visualization is a fun part, like a OpenGL or some charts (D3js, EChart, and etc)
