About

I grew up in Mongolia, where my parents worked tirelessly to give me access to education most Mongolians coudn't get. That disparity shaped everything I've built — from Ertech, bringing educational content to Mongolian speakers, to Garage, teaching non-technical people to build with no-code and AI. I care about using technology to open doors for people who otherwise wouldn't have access.
