FAQ
What is the difference between REST and GraphQL APIs?
REST is simple and uses fixed endpoints, while GraphQL allows you to request only the data you need, which is ideal for complex apps.
How do you ensure my backend is secure?
I use strong security measures, including role-based access, data encryption, and secure authentication to protect your system.
How long will it take to complete my project?
It depends on the project’s complexity, but I will give you an estimated delivery time after discussing your requirements.
Do you offer frontend development as well?
Yes! If you need frontend development, I can also build the user interface (UI) using technologies like React, Angular, or Vue.js, providing a complete full-stack solution.
Can you help integrate third-party services like Stripe or PayPal?
Yes, I can integrate services like Stripe, PayPal, Google/Facebook logins, and more to enhance your backend.
Do you provide domain & hosting services?
Domain and hosting are typically registered in the client’s name and are their property. While we do not provide domain and hosting directly, we’re happy to assist you in choosing the best hosting provider or even handle the entire setup for you as part of a custom package. Feel free to reach out.
