I will build or integrate a rest API into your application


About this gig
Need a reliable REST API or API integration for your application?
I will build, integrate, or improve REST APIs for web and mobile applications. I can work with existing projects or develop backend functionality from scratch, with a focus on clean, maintainable, and well-structured code.
I can help with:
- REST API development
- CRUD endpoints
- Third-party API integration
- Database integration
- User authentication and authorization
- JWT authentication
- Input validation and error handling
- Payment API integration
- API debugging and bug fixes
- Postman testing and API documentation
- Backend deployment and hosting setup
- Docker configuration
I work with multiple backend technologies, including Node.js/Express, Django, ASP.NET, Java/Spring Boot, JavaScript/TypeScript, Python, C#, and Java.
Please contact me before ordering if you have a larger or more complex project so we can determine the appropriate scope and package.
I aim to deliver functional, readable, and maintainable backend solutions that can be easily integrated into your application.

FAQ
What information do you need before starting?
Please provide your project requirements, preferred technology or existing tech stack, required API endpoints or integration details, database requirements, and any relevant documentation or existing source code.
Can you work with an existing project?
Yes. I can add new API functionality, integrate third-party services, fix backend issues, or improve an existing application.
Which backend technologies do you work with?
I primarily work with Node.js/Express, Django, ASP.NET, and Spring Boot using JavaScript/TypeScript, Python, C#, and Java. I am also open to working with other technologies depending on the project.
Can you connect the API to a database?
Yes. I can integrate APIs with SQL or NoSQL databases such as PostgreSQL, MySQL, MongoDB, and Firebase.
Can you implement authentication and authorization?
Yes. I can implement features such as login, registration, JWT authentication, protected endpoints, and role-based authorization.
Can you integrate a third-party API?
Yes. I can integrate external APIs and services into your existing backend or application, provided the service offers the necessary API access and documentation.
Will you provide API documentation?
Yes. API documentation or a Postman collection can be provided depending on your selected package or extras.
Do you provide deployment or hosting setup?
Yes. Backend deployment and hosting setup can be added as an extra service. Please contact me first with your hosting platform and application requirements.
Can you build an entire backend for my application?
Yes, depending on its size and complexity. For larger backends with many endpoints, integrations, or complex business logic, please contact me before ordering so I can provide an appropriate scope and price.
Should I contact you before placing an order?
For small and clearly defined tasks, you can order directly. For existing codebases, custom integrations, or larger projects, contacting me first is recommended to ensure the package matches your requirements.
