What is Backend Development?
Backend development is the server-side logic that powers your website or app — handling data storage, user authentication, API requests, and integrations with third-party services. It's the invisible infrastructure that makes everything work.
I build clean, secure, and scalable backends using Node.js (Express), Python (FastAPI/Flask), or PHP (Laravel), with both SQL and NoSQL database options.
What's Included
- RESTful API design and development
- Database architecture (PostgreSQL, MySQL, MongoDB)
- User authentication & authorization (JWT, OAuth)
- Server-side logic & business rules
- Third-party API integrations (Stripe, PayPal, Google, etc.)
- Data validation & sanitization
- Security best practices (CORS, rate limiting, encryption)
- API documentation (Swagger / Postman)
Process
Requirements & Architecture
We define the data model, API endpoints, and system architecture based on your application needs.
Database & API Setup
Database schema is designed and API routes are built with proper validation and error handling.
Integration & Testing
APIs are tested with unit and integration tests. Frontend integration is verified end-to-end.
Deployment & Documentation
You receive the deployed API, documentation, and a Postman collection for testing.
