I will build a secure jwt authentication API with node js and express
Shazzad Hosen
About this gig
Need a secure login system for your app without the risk of leaked tokens, broken sessions, or messy auth code? I build authentication APIs in Node.js and Express that handle it right the first time.
What I Offer:
- User registration, login, and email verification flows
- JWT authentication with refresh token rotation
- Server-side token validation to prevent replay attacks
- Short-lived access tokens to minimize exposure if compromised
- Role-based access control for protected routes
- Clean, fully documented REST endpoints ready to drop into your app
- MongoDB, MySQL or PostgreSQL integration
Why Work With Me:
- Security-first approach to every auth flow I build
- Currently running this exact pattern in production, live on Render
- Documented endpoints with clear request/response schemas no guesswork for your team
- Fast, clear communication I'll confirm scope before we start, no surprises later
Let's get your auth system built right. Message me your stack and requirements to get started.

I build secure, production-ready backend systems using Node.js, Express, and Fastify — REST APIs, auth flows, and AI-integrated features.
I focus on what's easy to get wrong: JWT auth with refresh token rotation, Redis rate limiting, and clean database design (MySQL, MongoDB, PostgreSQL). Recent work: a production auth API deployed on Render, Aiven, and Upstash, plus LogForge, an AI log intelligence platform.
I also fix backend issues in AI-generated apps (Lovable, Bolt.new, Replit). Pursuing a B.Sc. in Physics alongside. Open to freelance work, async-first.
