Yuhan Lee

My name is Yuhan 宇涵

I grew up in Taiwan and Canada. I now live in Berlin. I'm a front-end developer with 7 years of experience in web and mobile development. I currently work at Miro as a Software Engineer on hybrid mobile applications. When I'm not coding, I enjoy bouldering, playing badminton, and knitting.

On the side I'm an indie developer — I built Knotty, a mobile app that helps knitters and crocheters follow charts without losing their place.

This is my second wood work project building a dog bed for a dog I'm adopting. I decided to make this dog bed so the dog won't feel too low from the bed. The bed was built from a used block palette with cedar wood table top.
