FAQ
Can you integrate my API with a third-party service or frontend app?
Yes. I have experience integrating APIs with Angular frontends, payment gateways, email services, and third-party REST APIs. Share your integration requirements and I'll confirm what's possible.
Will the API be secure?
Yes. I implement JWT authentication, input validation, and proper error handling as standard. I also follow OWASP best practices to prevent common vulnerabilities like SQL injection and unauthorized access.
Do you provide documentation?
Yes. Every delivery includes a Postman collection for testing. The Standard and Premium packages also include Swagger/OpenAPI documentation so any developer can explore and test your API immediately.
Can you work with my existing database or do I need a new one?
Both. I can build an API on top of your existing SQL Server database, or design a new database from scratch based on your requirements. I'll adapt to whatever situation you're in.
