I'm a frontend engineer at Toss Bank, working on compliance products since January 2024.

I build customer-facing experiences and internal tools for compliance operations serving both individual and corporate customers.

• Customer-facing: KYC (customer due diligence) and FATCA/CRS (tax residency self-certification).
• Back-office: KYC reviews, end-to-end FATCA/CRS operations (reviews, regulatory reporting, and ongoing submissions), AML, STR/CTR (transaction reporting), and watchlist screening.
• Frontend engineering: Performance optimization, shared UI architecture, monorepo tooling, and developer experience.

I enjoy making complex domain logic easier to understand and maintain, without losing the details that matter.
