About

I build web applications and support the systems people depend on. My experience spans government platforms, startup products, and enterprise smart factories. At LG Sinarmas, I support operations for 12+ US EV-battery smart factories and work with engineering teams in Korea and the US to resolve production incidents. Previously, I co-founded Byte Labs Technology, delivering client applications and building services with Java and Go.
