How do you ensure the security of APIs?
I follow industry-standard best practices for API security, including token-based authentication (OAuth2, JWT), rate limiting, input validation, and secure data transmission using HTTPS.
Do you provide API documentation?
Yes, I deliver comprehensive API documentation to ensure easy integration and use by developers, including examples, endpoints, and parameters.
What programming languages and tools do you use for API development?
I primarily use Node.js, .Net, Python, and Go for API development, along with tools like Postman for testing and debugging. I can also work with AWS Lambda and serverless frameworks.
Can you help maintain and scale the API after development?
Yes, I offer ongoing support, maintenance, and performance optimization to ensure your API remains reliable and scalable as your needs grow.
How long does it take to develop an API?
The timeline depends on the complexity of the API. A basic API can take 1-2 weeks, while more complex integrations or custom APIs may take 3-4 weeks.
