Muhammad Ahmad
About this gig
Need a reliable backend API for your SaaS product, web app, or mobile application?
I will build a secure REST API using Node.js, NestJS, and TypeScript. Your backend will be modular, documented, and structured around your business workflow.
What I can deliver:
- CRUD and custom business modules
- PostgreSQL, MySQL, or MongoDB setup
- JWT authentication and protected routes
- Role-based access control
- Validation, filtering, sorting, and pagination
- Swagger documentation and Postman testing
- Webhooks and third-party API integrations
- Structured error handling
- Docker and deployment assistance when included
Tech stack: Node.js, NestJS, TypeScript, TypeORM, PostgreSQL, MySQL, MongoDB, JWT, Swagger, and Postman.
Each package has fixed module and endpoint limits. Payments, AI integrations, microservices, real-time systems, and large existing codebases require a custom offer.
Please message me before ordering so I can review your workflow and confirm the correct package.
Backend development only. React or Next.js dashboard development is available through my separate Gig

FAQ
What counts as one API endpoint?
Each unique HTTP method and route counts as one endpoint. For example, GET /products and POST /products are counted as two separate endpoints.
What counts as one business module?
One business module represents one main resource or feature, such as Products, Orders, Users, Appointments, Bookings, or Tasks. A standard CRUD module usually includes create, list, view, update, and delete operations.
Which databases do you support?
I work with PostgreSQL, MySQL, and MongoDB. PostgreSQL is usually recommended for applications with structured relationships and transactional data, while MongoDB can be suitable for flexible document-based data.
Is JWT authentication included?
JWT authentication is included in the Standard and Premium packages. OTP, social login, email verification, and password-reset email flows may require a Gig Extra or custom offer.
Will the REST API be documented?
Yes. Every package includes Swagger documentation for all endpoints delivered within the agreed scope. Standard and Premium packages also include a Postman collection.
Do you provide role-based access control?
Basic role-based access control is included in the Premium package. It can include roles such as Admin, Manager, and User. Complex permission rules may require a custom offer.
Can you integrate third-party APIs or webhooks?
Yes. The Premium package includes one standard third-party API or webhook integration. Payment gateways, AI services, CRMs, or complex integrations must be reviewed before ordering.
Is frontend development included?
No. This Gig covers backend API development, database setup, authentication, and server-side business logic. React or Next.js frontend and dashboard development is available through my separate Fiverr Gig.
