Develop and integrate RESTful or GraphQL APIs to enable seamless data exchange between web and mobile applications.

Description

APIs (Application Programming Interfaces) are essential for enabling seamless communication between different software applications, whether for web, mobile, or enterprise solutions. As a freelance API developer, your role is to design, build, and integrate APIs that allow applications to exchange data efficiently. You’ll work with RESTful or GraphQL APIs, ensuring proper authentication using OAuth, JWT, or API keys. API development also includes writing well-documented endpoints, handling request validation, and implementing rate-limiting for security. Integration tasks may involve connecting third-party services like payment gateways (Stripe, PayPal), cloud storage (AWS, Google Cloud), or social media platforms (Facebook, Twitter). Testing APIs using tools like Postman or Swagger ensures smooth performance. Businesses require API development to automate processes, enable real-time data sync, and enhance software interoperability. By offering API development and integration services, you help clients improve application efficiency, scalability, and user experience.
