FAQ
Who owns the code after the project is finished?
You receive full ownership of the source code and all intellectual property (IP) rights after the final payment. The code will be delivered to your own GitHub repository, giving you complete control and security.
How do you protect my data and project confidentiality?
Confidentiality is a priority. I can sign a Non-Disclosure Agreement (NDA) if needed. All work is developed in your private GitHub repository, and only I have access to the code during development. No data or code is shared with third parties.
What happens if I need changes after delivery?
Each package includes a number of revisions (1 for Basic, 2 for Standard, 3 for Premium). If you need more changes after that limit, you can purchase the "Additional Revision" extra for $10, which includes 1 day of work.
How does payment work and when do I receive the code?
Payment is made through the Fiverr platform, which keeps the funds secure until final approval. The code is only delivered to the GitHub repository after the payment is confirmed and the order is marked as complete.
Can you deploy the API to production?
Yes, I offer deployment support as an extra service for $25. I can help you publish the API on platforms like Vercel, Heroku, AWS, or Railway, and ensure everything is configured correctly.
What types of tests do you include in the service?
The Premium package includes unit tests with Vitest to ensure the API works correctly. The tests cover the main features and help prevent bugs. The Basic and Standard packages do not include automated tests.
Will the code be commented and easy to maintain?
Yes, the code is written with best practices and includes detailed comments in the Standard and Premium packages. This ensures that you or any other developer can understand and maintain the code in the future.
