I will build a nodejs nestjs backend rest API with typescript
Mohammad Moiz
About this gig
Need a reliable backend API for your web app, SaaS product, mobile app, or internal business system?
I will develop a clean and maintainable REST API using TypeScript, Node.js, and NestJS. With 5+ years of professional software-engineering experience and current Tech Lead responsibilities, I focus on clear architecture, dependable implementation, and practical documentation.
Depending on your selected package, your API may include:
REST endpoints and business logic
PostgreSQL database integration
Request validation and error handling
Authentication and role-based access
Swagger/OpenAPI documentation
Automated tests
One approved third-party API integration
Deployment assistance
Package limits apply to endpoints, database entities, integrations, and revisions. A revision covers corrections within the agreed requirements; it does not include new endpoints, entities, roles, integrations, or changed business logic.
Not included unless agreed through a custom offer: complex legacy-system work, multi-tenant architecture, payment systems, real-time features, major data migrations, frontend development, cloud infrastructure, ongoing maintenance, or third-party fees.
Please contact me before

FAQ
What counts as one API endpoint?
One unique HTTP method and route counts as one endpoint. For example, GET /users and POST /users count as two endpoints.
What counts as a database entity?
A database entity is one primary business model or table, such as User, Product, Order, or Appointment. Supporting join tables will be reviewed according to complexity.
Does the Gig include authentication?
Authentication is included in the Standard and Premium packages. Basic authentication is not included in the Basic package unless arranged through a custom offer.
What does role-based access include?
The Premium package includes a bounded role-based access setup for the agreed workflows. Complex permission matrices or multi-tenant authorization require a custom offer.
What qualifies as one third-party integration?
One approved external service with a clearly defined workflow, such as sending data to or retrieving data from one documented API. Payments, poorly documented APIs, and multi-system workflows require review before ordering.
What does a revision include?
A revision corrects work that does not match the agreed requirements. New endpoints, entities, integrations, roles, or changed requirements are additional scope.
Are deployment and hosting included?
Premium includes reasonable deployment assistance for one agreed environment. Hosting accounts, cloud resources, domains, subscriptions, and ongoing infrastructure costs are paid by the buyer.
Do you provide the source code?
Yes. Source code for the agreed deliverables is included in every package. Third-party libraries remain subject to their respective licenses.
Can you work with an existing backend?
Yes, after reviewing its architecture, code quality, dependencies, and documentation. Existing or legacy systems may require a custom offer.
Do you also build the frontend?
This Gig covers backend API development. Frontend development is not included and should be discussed separately if required.
