FAQ
What information do you need to get started?
I’ll need a clear list of required APIs (endpoints), details about your database (if any), authentication preferences, and any specific technologies or third-party integrations you want. A small project brief or sample data structure helps me get started faster.
Will you provide API documentation?
Yes, I always include complete API documentation (Postman or Swagger format) so you and your team can easily understand and test each endpoint.
Can you integrate my APIs with a database?
Absolutely! I work with both SQL (MySQL, PostgreSQL) and NoSQL (MongoDB) databases. I’ll design efficient models and relationships tailored to your app’s requirements.
How do you ensure API security and performance?
I follow best practices such as input validation, JWT authentication, HTTPS, rate limiting, and error handling. I also optimize queries, caching, and structure for scalability and fast response times.
Can you deploy or host the backend for me?
Yes, I can assist with deployment on platforms like AWS, Heroku, Render, or VPS. I’ll help set up the environment and ensure your backend runs smoothly in production.
