Anonymized case study. Client name and identifying metrics are withheld. Patterns reflect representative senior .NET programs.
Executive summary
Field technicians for a regional utilities provider relied on paper and a brittle Xamarin app. Incidents spiked when API changes broke mobile validation rules divergent from the server.
The challenge
Spotty rural connectivity. Duplicate work orders after partial sync failures. Separate mobile and API validation logic drifted every sprint.
Technical approach
MAUI with MVVM, offline SQLite queue, shared validation library packaged for API and client, background sync with server-wins conflict rules for master data, and device lab coverage on mid-tier Android hardware.
Outcomes
Technicians completed full shifts offline. Sync reconciliation errors became actionable in a support dashboard. Release cadence aligned mobile and API in one pipeline.
