CHANN 
Who am I
I'm CHANN(Heechan Bak), a 28-year-old developer living in Seoul, South Korea. I usually produce code, photograph, article, and design. I ride a bicycle or watch movies as a hobby. Sometimes I chitchat on Twitter or brag about the food what I eat on Instagram. Check my Blog for more information.
I'd like to make something when I was young, So I made my own homepage using HTML, PHP when I was ten years old in 2000. That's the first step of my career. Next year, I made flip-flop card game and fake cultureland-gift-ticket generator using Visual Basic.
Now I'm interested in Python, Golang, Node.js, ...and all kinds of programming. But my major focus is on server, container orchestration, web, machine learning, automation, dApp, etc. I also have skills in other fields like design and midi composition. I am enthusiastic person with fast adapting skills in new environments.
