Backend and API Development
I build the engine behind your product: secure REST APIs, authentication, payment processing, and well designed databases that keep your data safe and your app fast.
Using Node.js and NestJS with PostgreSQL or MongoDB, I deliver backends with proper validation, error handling, and documentation, ready to power your web and mobile apps.
What's Included
- REST API design and development
- Authentication and authorization (JWT, OAuth)
- Payment integration (Stripe)
- Database design (PostgreSQL, MongoDB)
- Third party API and cloud integrations
How We'll Work Together
Requirements & data modeling
What data you have, who touches it, and how it flows. The schema is designed before any endpoint exists.
API contract first
Endpoints, payloads, and errors agreed up front so your frontend or mobile team can build in parallel.
Build with validation & tests
Every endpoint ships with input validation, proper error handling, and tests, not just happy paths.
Security & performance pass
Auth flows, rate limiting, and slow-query checks before anything faces the internet.
Deploy with CI/CD
Automated deployments with rollbacks, so shipping updates is a non-event.
Docs & handover
Swagger documentation and a walkthrough so any developer can pick it up after me.
What You Get
- A documented REST API
- Secure auth with JWT and OAuth 2.0
- Payment processing with Stripe Connect
- A well structured database schema
- Cloud deployment and monitoring
