What I'm looking for

I’m looking to keep owning backend architecture and security-critical API work—shipping OAuth 2.0-backed REST services and production NPM packages with reliable routing and rate limiting.

I architect, build, and ship backend systems end-to-end with Node.js, Express.js, TypeScript, and PostgreSQL—owning REST APIs and OAuth 2.0 flows from design through delivery.

At PlayKit, I led the backend architecture for a playlist migration platform between Spotify and YouTube Music, including secure token refresh, the full REST API surface, and a fuzzy track-matching algorithm integrated with the React.js frontend.

I also design security-focused infrastructure, from a zero-dependency OAuth 2.0 NPM security package for signed OAuth state parameters to a fault-tolerant routing gateway with health checks, rate limiting, and production-grade middleware releases.
