FAQ
What do I need before ordering?
You only need an AWS account (free tier works) and a clear idea of what your API should do — for example, the endpoints you need or what kind of data it should manage.
Can you create the AWS account for me?
Yes — I can help you set up your AWS account and configure all required services (Lambda, DynamoDB, etc.) for you. The account will be created using your information, and you’ll have full access and ownership once setup is complete.
Will you deploy everything on my AWS account?
Yes. I will deploy the API to your AWS environment, fully configured and ready to use. You’ll have full ownership and access to all resources.
Can you include authentication and user login?
Yes, I can integrate AWS Cognito for secure login, signup, and JWT token-based authentication — included in the Standard and Premium packages, or available as an extra
What about file upload or image storage?
That’s possible with AWS S3 integration — included in the Premium package or as an extra add-on.
Can I get email notifications from my API?
Yes, I can connect AWS SES (Simple Email Service) so your API can send automated or transactional emails (optional extra custom offer).
Do you provide API documentation?
Yes — a Postman collection or Swagger/OpenAPI documentation is included in the higher tiers or can be added as an extra.
Do you offer updates or maintenance after delivery?
Yes, I can provide post-delivery updates or improvements as a separate Custom Offer. This ensures your API stays aligned with your app’s growth.
I need something different — can you customize it?
Absolutely. If you need a custom setup (more endpoints, multiple DynamoDB tables, custom roles, or third-party integrations), just message me before ordering. I’ll prepare a Custom Offer tailored to your project.
Is my data safe?
Yes — all configurations follow AWS best practices for security, access control, and IAM permissions. Your data and credentials stay private and under your control.
