About this gig
Need a secure, documented REST API or a solid backend for your app? I build production-ready backends from scratch, tested and
documented.
Backend developer with production APIs running in SaaS, e-learning and B2B marketplace platforms.
What I build:
- REST APIs with Node.js, NestJS or Express (TypeScript)
- Authentication: JWT, OAuth, role-based access
- Database design and integration (PostgreSQL, MySQL)
- Integrations: payment gateways, webhooks, external APIs
- Swagger/OpenAPI documentation included
Every project includes:
- Clean, scalable architecture with validation and error handling
- Security best practices on every endpoint
- Full source code via Git or ZIP
How I work:
- Clear scope and price agreed before starting
- Sandbox first for third-party integrations, then production
- Revision rounds defined per package
- 7-day support window after delivery
Please note: this gig is backend only for complete web apps with frontend, check my other gigs. Deployment is quoted as a separate
service.
Message me with what your API needs to do and I will send you a clear quote.

FAQ
What exactly counts as an "endpoint"?
Each route and method (e.g., GET /users and POST /users are two endpoints). We define the full list before starting so the scope is clear.
Which stack do you use?
Node.js with NestJS or Express, in TypeScript, with PostgreSQL or MySQL. Swagger/OpenAPI docs included. Laravel/PHP is also available if your project requires it.
Can you integrate payments or external services?
Yes: Stripe, PayPal, Wompi and other third-party APIs, with webhook signature verification. Integrations are validated in sandbox first; going live depends on your accounts and credentials being ready.
Do you deploy the API?
Deployment is quoted as a separate service. The standard delivery is the full source code with setup instructions.
How many revision rounds are included?
1 in Basic, 2 in Standard, 3 in Premium. Changes outside the agreed scope are quoted separately.
Can we have a call?
All communication stays on Fiverr chat. I deliver demos as screen recordings (Swagger or Postman walkthroughs) and updates at key milestones.
