FAQ
What information do you need to start working on my API?
I’ll need a clear description of your requirements, the expected functionality of the API, any third-party integrations you need, and details of your preferred database (if applicable). If you already have a system, sharing the existing codebase or documentation will help speed up development.
Do you provide both frontend and backend development?
Yes! While this gig focuses on backend APIs, I also have expertise in frontend development (React.js, Next.js) and can deliver a complete end-to-end solution if required.
Will my API be secure?
Absolutely. I follow best security practices, including input validation, authentication & authorization (JWT/OAuth2), rate limiting, and HTTPS setup to ensure your API is secure.
Can you integrate my API with third-party services?
Yes, I can integrate your API with payment gateways, messaging platforms, social logins, analytics tools, and other third-party services.
Do you provide API documentation?
Yes. I can provide well-structured API documentation using Swagger / OpenAPI so your team can easily understand and use the API.
Will my API be scalable for future growth?
Definitely. I design APIs with scalability in mind so you can easily add features and handle more users without major rework.
Can you deploy the API to a live server?
Yes, I can deploy your API to hosting services such as AWS, DigitalOcean, Heroku, Vercel, or your preferred cloud provider.
What if I need changes after delivery?
Minor changes or bug fixes related to the initial requirements are included. For additional features or major changes, we can discuss an extension or a new order.
Do you write tests for the API?
Yes, I can write unit and integration tests (Jest, Mocha, Supertest) to ensure your API works reliably.
Can you connect my API to a mobile app or website?
Yes. I can build APIs that are fully compatible with Android, iOS, and web apps, ensuring smooth communication between frontend and backend.
