Crossing Over
summary
Builds a C# Xamarin-backed gifting microservice and wires it into a two-year-old client codebase, adding unit and integration tests at the service layer and testability hooks on the client. Releases fail first because users misinterpret the UI, a redesign and feature flag fix rollout succeeds, then revenue dips. Investigation with a SQL query that found the bug reveals a logic error that grants a gift to all friends instead of a single recipient, patching restores normal purchase behavior.
