Hi there, I’m Ikwhan.

Developing web products since 1998
Currently, Software Engineer @Google
CMU Alumni, Ex-Startup Founder @Urhyme

For several years, I’m an expert in full-stack web development from the scratch, dealing with ETLs, APIs, Serverless, UX, and product management. I was a founder and CTO of several startups in the Bay Area for developing future-oriented products (Big Data, EduTech, Blockchain) I’m inspired by balancing between cutting-edge and old-school CS theories and algorithms.

Korean to the core??, I like to find the hole-in-the-wall gourmet places when traveling around the world with my lovely wife.
