### story
Started from developing MMOG, I consistently took part in building high throughput, low latency server system for gaming, and was interested in providing brand-new way to communicate people, not just by implementing game feature, but also preparing fundamental framework, deploying workflow, manage and educating team member (build tool for it if necessary). 
I'm more enthusiastic with it because rise of AR and blockchain technologies makes innovative way of virtual communication easily embedding to real society, in the perspective of rewarding and accesibility.
