Greenfield work against six systems: five on code old enough to be AngularJS, and one API being built in parallel, so the target moved while we integrated with it. The patterns established there are what the rest of the module follows.

The team's designated champion. WCAG is checked at architectural review, where it is cheap, rather than at audit, where it is a rewrite.

A multi-tenant database carrying more than twenty schema variations: deployments were unpredictable and data integrity was at risk. The migration patterns were unified and automated checks put in front of them. The drift went, and it has not come back — the checks are what keep it out.

The data collection moved in-house onto PostgreSQL through the Django ORM, HIPAA-compliant throughout. The vendor's bill went to zero, and the product team could iterate on the flow for the first time.
