I will build a scalable saas backend with nodejs postgresql stripe and auth

Need a SaaS or AI backend that survives real users, real payments, and real investor scrutiny?

You don't need "just an API." You need a backend that won't get rewritten in 6 months.

That's what I build.

What you walk away with:

• Production auth JWT, RBAC, session security done right
• Cleanly modeled Postgres or MongoDB schema (designed, not improvised)
• Documented REST API + Swagger / Postman collection
• Stripe integration with idempotent webhooks (no double charges, ever)
• AI integrations with rate limits + token tracking (OpenAI / Claude / RAG)
• Background jobs, Redis caching, and realtime where it matters
• Deployed live with CI not "works on my laptop"
• Source code, README, and handover so your next dev ships day one

Stack: Node.js · Express · NestJS · FastAPI · Next.js · PostgreSQL · MongoDB · Redis · Stripe · Socket.io

Best for: founders and early-stage startups who want their backend built once, properly.

Message me before you order. Send a short project summary and I'll confirm scope, recommend the right tier, and give you a realistic delivery date no charge, no commitment.

Let's build it right the first time.
