Jay Mishra

Backend-leaning full-stack developer. I build REST APIs, OAuth flows, and the middleware that keeps two systems that were never meant to talk to each other, talking to each other.

GET/about 200 · text/html

I'm currently finishing a B.Tech in Electrical & Electronics Engineering at SJBIT, Bangalore — expected 2027 — while building production-grade backend systems on the side. Most of my time goes into Node.js and Express: REST API design, database modeling, and the authentication plumbing most people never think about until it breaks.

My main project right now is PlayKit, a full-stack playlist transfer platform that moves libraries between Spotify and YouTube Music — OAuth 2.0 on both ends, token refresh handling, and fuzzy track-matching across two catalogs that don't agree on anything.

Alongside that, I've published a handful of open-source npm packages — a configurable rate limiter, an OAuth state manager, and a music-link parser — with 300+ combined downloads.

The thing I spend most of my time on. Everything else lives under Open Source.

PlayKit

Transfer playlists between Spotify and YouTube Music. Full-stack app handling OAuth on both platforms, fuzzy track-matching across two catalogs that don't agree on metadata, and secure token refresh — so a migration just works instead of needing babysitting.
