What the work looks like when it is finished

Four builds, written up honestly: what the problem actually was, what got built, and what it deliberately does not do.

The pattern

Build the platform layer once, then put products on it

The first custom app is expensive because you are paying for OAuth, token handling, install and uninstall flows, webhooks and data sync. The second, third and fourth are cheap, because that work is already done and does not get rewritten.

That is why two apps exist rather than one, and why the second took a fraction of the time.

Something similar on your account?

Start with the audit

A written architecture record and a staged plan, useful whether or not I build the rest.
