SloveniaWhat I'm looking for
I'm currently building and publishing a mobile OTA app for flight search, purchases, and post-booking support as a self-employed mobile software engineer. I migrated it from deprecated Xamarin to modern .NET 9 and .NET 10 SDKs, delivered new features and screens with AI tools, and maintained third-party iOS and Android libraries.
At AltexSoft, I developed mostly mobile, few backend and desktop applications from project setup through implementation. My work included ecommerce, travel booking, presentation coaching, live volleyball scoring, radio streaming, financial services, and data-processing products.
I've built custom iOS and Android interfaces, native library bindings, offline synchronization, push and local notifications, social integrations, analytics, Google Maps, geolocation, automated tests, and unit tests. I also worked with ASP.NET APIs, LINQ, Entity Framework, MS SQL Server, WPF, Excel reporting, and parallel and asynchronous calculations.
Earlier, I developed and supported internal ERP software at Kryukovsky Railway Car Building Works, including a product cost accounting system for collecting, analyzing, and calculating planned product costs.
