Can we hand off to our own engineering team after launch?

Yes, that is a common path. We hand over the repository, full documentation, runbooks, and a written post MVP roadmap at launch. The codebase is clean Laravel with Pest tests and Larastan static analysis, which makes onboarding an in house engineering team straightforward. Many clients keep us on a short term Dedicated Developer engagement during the first three months of in house team ramp up, then transition fully.
