Product managerIdentity & SecurityHuman-Centered AI
From ISO 19092 biometric security work to identity systems for 60+ financial institutions and 14 airports, I've built that trust at national scale. Now I design AI agent governance people can see into, so they can delegate with confidence.
01Featured project
In 2022 KFTC launched Korea's first cross-industry biometric ID, which lets a person enroll a palm once at one of 12 banks and use it at 14 airports. I led the go-to-market and the rollout, coordinated the banks, the airports and the scanner hardware vendor, and set privacy-first rules for handling palm-vein and facial sensor data.
02Also shipped
I led a KYC identity platform serving 500K+ daily active users across 60+ financial institutions. I owned the API integration and compliance with GDPR, eIDAS and PSD2, and the platform reached 150% revenue growth.
A biometric payment system that runs without a card network, shipped in one month with zero false charges.
