I will build a full stack fastapi nextjs custom saas website

During the development, I can host your application temporarily on my own personal servers, but you will need to own your own infra in order to deploy this. I will, of course, help you deploy the application on whichever provider you go with.

Yes, after launch, you will receive a FREE maintenance and support period of 1-3 months depending on the size and scale of your project. After that free maintenance period, if you need any other support, that will be paid.

And this depends on the size and scale of your project, but pricing will usually be milestone-based. Your project will be divided into a list of milestones and charged separately. Project timeline also entirely depends on its complexity.

After the project is complete and all payments have been settled, you will receive ownership of the entire codebase and all the assets that I produce. What you do with them afterwards is entirely up to you.

Generally, the more involved you are, the better the product is going to be. You will receive regular updates about the development progress. The best thing you can do is provide timely feedback on those development updates.
