Yes! I can create both RESTful and GraphQL APIs based on your needs. Just let me know your preference, and I’ll design the backend accordingly.
Do you offer deployment services?
Absolutely! I can deploy your backend on platforms like AWS, Heroku, or DigitalOcean to make sure your API is live and accessible.
How do you ensure the security of the API?
I implement industry-standard security practices, including JWT/OAuth for authentication, role-based access control, data validation, and rate limiting to secure your API against threats.
Will you provide documentation for the API?
Yes, all packages include basic documentation. For more detailed API documentation, you can select it as an additional service.
Can you help with integrating the API into my front end?
While this gig focuses on backend development, I can provide integration support as an extra service. Please reach out to discuss your specific needs.
