What I'm looking for

I'm looking to help organizations create and optimize cross-platform applications, modernize mobile and backend systems, and improve performance through scalable architecture, API integration, and automated delivery.

I've led the migration and development of enterprise mobile applications at Balidea and Abas BS, using Xamarin, .NET MAUI, C#, and React to deliver solutions from requirements through automated deployment.

At Abas BS, I was Product Owner and main developer for multiple apps, building integrations with Abas ERP APIs and modernizing mobile and backend platforms with .NET Core and Entity Framework. I've also developed for specialized Zebra devices and integrated services including Google Maps, Firebase, Azure OCR, Azure Media Services, and App Center Analytics.

As a freelance technical consultant, I optimize cross-platform enterprise applications through scalable architecture, MVVM, external API integration, CI/CD, and performance improvements. I also enjoy creating games with Unity and C#.
