Choi Yeongjae

software engineer · CTO @ Actibooky Inc.

I have been building software for 20+ years: Cafe24, Bunjang and Deepsearch, then seven years running my own company. Today I am CTO at Actibooky Inc., working on small AI models that people can use just by speaking, and on an open standard that helps AI agents understand the web on their own.
