About Me

I’m a Senior Software Engineer with 5+ years of experience building production systems across logistics, transit data, and document platforms. I work primarily in TypeScript and NestJS, with strong full-stack depth in React and Next.js — always grounded in clean architecture, domain-driven design, and event-driven microservices.

I collaborate closely with stakeholders to align technical decisions with business goals, and I’ve led teams through aggressive delivery timelines without compromising on code quality or security compliance.

Led Amazon SP-API compliance negotiations, implemented metered billing integrations, and drove JINDO frontend modernization from React 16 to Next.js with Radix UI and Panda CSS.
