About this gig

Need a clean, scalable backend for your product?


I will build or upgrade a production-ready NestJS/Node.js REST API for SaaS use cases.


What you get (based on package):

- Well-structured NestJS code (controllers/services/modules)

- JWT authentication + optional RBAC (roles/permissions)

- PostgreSQL schema + migrations

- Proper validation, error handling, and API best practices

- Swagger/OpenAPI documentation

- Optional Redis caching for performance


What I need from you to start:

- Brief about the product + core entities (tables)

- Endpoint list OR user flows

- Existing repo access (if any) + environment details

- Any integrations (Stripe, email, S3, etc.)


Important:

- This gig is backend/API only (no UI design).

- Message me before ordering if scope is unclearIll confirm the best package.

Full‑stack engineer focused on backend-first SaaS products. I build production NestJS/Node.js APIs (auth, RBAC, billing-ready), scalable PostgreSQL schemas, and Redis caching for high performance. I also deploy reliably on AWS using Docker and (when needed) Kubernetes with clean CI/CD-friendly setups. I’ve been building web products since 2021, and I care about clean architecture, clear communication, and on-time delivery.
