Develop or integrate a custom API for your app or website

About this ad

Need to connect your app with external services or build a custom API from scratch? I’ve got your back. I offer API development and integration services tailored to your business logic so you can automate processes, sync data, or extend functionality without lifting a finger—except to hire me.

Whether it's integrating third-party APIs like Stripe, SendGrid, or Google APIs, or developing custom REST APIs for your web or mobile application, I deliver clean, secure, and scalable solutions. I work with Node.js, Express, PHP, and Python, and can also hook into your existing backend stack.

I can develop custom APIs using REST and JSON, integrate any third-party APIs, implement secure authentication methods like OAuth2, API keys, or JWT, and set up proper error handling and logging. The code will be clean and easy to maintain, with clear documentation to make future updates a breeze. I can also include Postman collections for easy testing if needed.

I write APIs with both developers and performance in mind—scalable endpoints, secure requests, and consistent structure. Whether you need a full backend or just want to automate something small, I’ll help you get it done fast and right
