## About

```text
At Clearion - An ARCOS Company, I developed a cross-platform field service application for electrical utility networks, first with Xamarin.Forms and later .NET MAUI. I implemented Esri-powered maps and real-time field-worker visualization, along with background location tracking across iOS, Android, and Windows.

I built offline-first workflows with SQLite persistence and synchronization with Esri backend services, including conflict handling and recovery. I also optimized memory use and led key parts of the Xamarin.Forms to .NET MAUI migration.

At eBillity, I developed a cross-platform employee time-tracking application and migrated it from Xamarin.Forms to .NET MAUI. My work included location tracking, offline storage and synchronization, and integrations for Stripe payments, OAuth, and PDF invoices; I also used Claude Code and Codex for code generation, refactoring, and debugging.
