I'm a Staff Engineer and AI Product Builder — designing systems that power real products.
I spent 12 years at NBT as Director of Engineering, where I built Korea's #1 rewarded ad platform, AdiSON — scaling it to 10M+ MAU and 45% market share, and leading the engineering organization through a successful KOSDAQ listing.
Now at Datarize, going back to zero to one — working across Data, Backend, and AI to build systems that connect the right products to the right customers.
Great engineering isn't about shipping code — it's about creating value that actually matters. If any of this resonates, let's grab a coffee.
