You will get Node.js & NestJS REST or GraphQL API — Secure & Scalable Backend
Project details
I'll build a secure, scalable, production-ready backend API in Node.js and NestJS — REST or GraphQL — using clean architecture your team can keep building on after handover.
With 5+ years building production SaaS across telehealth, fintech, and booking platforms, I've shipped real backend systems handling authentication, business logic, payments, and real-time features under actual load. Not tutorial code — systems that hold up in production.
What you'll get:
Well-structured REST or GraphQL API
JWT authentication and role-based access control (RBAC)
Solid database layer — PostgreSQL or MongoDB (Prisma / Mongoose)
Input validation and robust error handling
Full Swagger or GraphQL documentation
Clean, modular architecture — controllers, services, and modules cleanly separated
Optional Docker, CI/CD, and cloud deployment (AWS / Vercel / Render)
You get documented, tested, production-ready source code and a full walkthrough at handover — so your codebase stays maintainable as it grows, not just for the demo.

About Muhammad
Senior Full-Stack Developer | SaaS, AI & Payments (Next.js/NestJS)
Sialkot, Pakistan - 10:55 am local time
I specialize in taking products from architecture to production — not just writing code, but making the technical decisions that keep a platform scalable as it grows.
Recent work includes:
• Built an enterprise HRMS and multi-tenant SaaS platform (Next.js, NestJS, GraphQL, RabbitMQ, MongoDB) — implemented organization management, role-based access control, and scalable backend services.
• Built a SaaS court booking platform (NestJS, Next.js, Prisma, PostgreSQL, Stripe, AWS) — including scheduling logic, staff/business availability handling, and subscription billing.
• Built multi-tenant booking platforms (React admin panel, NestJS, MongoDB) with an embeddable booking widget that any business site can integrate — letting customers book based on staff and business availability, used across service-industry clients including salon/barber-style booking.
• Built a social/professional networking platform with real-time features, calendar integrations (Google/Outlook), and Stripe/PayPal payments.
• Built an AI-powered risk analysis SaaS using RAG pipelines and vector search.
I also build content-driven platforms using Payload CMS and Strapi — headless CMS setups, custom admin panels, and API-driven content management.
I'm also actively deepening my AI engineering skills — building hands-on with RAG pipelines, LLM integrations, and vector databases (Qdrant, pgvector) beyond client work, so I stay current as the AI tooling landscape moves fast.
Technical stack: Next.js, React, TypeScript, Node.js, NestJS, GraphQL, PostgreSQL, MongoDB, Redis, Prisma, Payload CMS, Strapi, Stripe/PayPal, OpenAI API, RAG/embeddings/vector databases, Docker, AWS.
If you're building or scaling a SaaS product and need someone who can own the technical side end-to-end — architecture, backend, integrations, and deployment — let's talk about your project.
Steps for completing your project
After purchasing the project, send requirements so Muhammad can start the project.
Delivery time starts when Muhammad receives requirements from you.
Muhammad works on your project following the steps below.
Revisions may occur after the delivery date.
Requirement review & API design
I review your needs and design the API structure, endpoints or schema, and database models before writing code.
Core setup
I set up the project with clean modular architecture, database connection, and configuration.
