I will build a scalable nestjs rest API with postgresql
Hamza Saddique
About this gig
Are you looking for a backend developer who actually understands production-grade NestJS architecture?
Hi, Im Hamza. I don't just write code that works; I engineer backend systems that scale. I specialize in building highly secure, maintainable REST APIs using NestJS, TypeScript, and PostgreSQL. Whether you need a simple microservice or a complex multi-tenant SaaS backend, I write clean code that follows strict architectural principles.
What I will build for you:
- Robust REST APIs using NestJS and TypeScript
- Secure JWT Authentication & Role-Based Access Control (RBAC)
- Optimized PostgreSQL database design (TypeORM or Prisma)
- Implementation of Guards, Interceptors, Pipes, and custom Decorators
- Automated API documentation (Swagger/OpenAPI)
- External integrations (AWS S3 for files, Nodemailer for emails)
- Deployment configuration (Vercel, Railway, Render, or VPS)
Real Project Proof: I recently architected a production-grade multi-tenant LMS SaaS. This required managing four distinct user roles (Admin, Instructor, Student, Manager), complex RBAC logic, and real-time data flows.
My Tech Stack: NestJS | TypeScript | Node.js | PostgreSQL | TypeORM | Prisma | JWT | Docker

FAQ
Can you connect the NestJS API to my React or mobile app frontend?
Yes. I build APIs that work with any frontend — React, Next.js, React Native, Flutter, or any client that consumes REST APIs. Just share your frontend requirements and I'll design the API responses accordingly.
Do you provide source code and documentation?
Always. Every delivery includes the full source code, a README with local setup instructions, and Swagger API documentation so your team can understand every endpoint.
Can you implement multi-tenant architecture?
Yes — this is one of my strengths. I have built a production multi-tenant LMS SaaS with NestJS. I can implement row-level or schema-level multi-tenancy depending on your requirements.
What if my project is larger than the packages listed?
Message me before ordering and I'll create a custom offer. I work on larger SaaS and enterprise-level projects regularly and can scope and price them accurately.
Can you work with an existing NestJS codebase?
Yes. Share your GitHub repository and I'll review the architecture before confirming the scope. I'm comfortable extending existing projects, adding modules, or refactoring code.
