>So how can you guys roll out a product in 3 months? How can you quickly pivot?

Tooling. To elaborate, if you're hand writing code to call an API, then you're doing to much. This is a 15 minute task at most, and that includes production level validation, security, etc. on both the client and server.

Also, basic code quality checks should be running non-stop in a separate terminal and automated tests should also be running. Plus the core automated tests should themselves be automated.

Developing an API is again a 15 minute task.

To be totally clear, proper tooling will take you from prototype to (early) production. Obviously, tooling does not write your application for you, but standing up a basic app where you can use the UI and move data to/from the backend needs to happen with a minimum of effort. Once the core design/structure is done, you can spend your time on value add activities such as UI customization, custom business logic, and so on.

Its relatively easy, but far more than 15 minutes. Think about authentication, design and testing.
