Hire the Best Xamarin Developers
in the United States

I have 18 years experience as a .Net developer. I have used a number of Microsoft technologies including C#, Xamarin, Maui, WinForms, WPF, Silverlight, WCF, ASP.Net, and SQL Server. Since April 2012, I've been working heavily with Xamarin, and started migrating to Maui in 2023. I've spent that time working on a team writing an enterprise application for existing customers to assist in their day-to-day operations. I've also written, been on a team, or took over 20+ applications in my personal time using both Xamarin.iOS, Xamarin.Android, Xamarin.Forms, or Maui. My professional job is a telecommuting employee. I've been working as a telecommuting employee since January 2012. This requires the ability to work without supervision and to be a "go getter".

25 years experience with 3 Microsoft certifications in Asp.net, C# and SQL. Full-stack Web and Mobile Developer - Developed 14 MVPs to date. Expert in .Net/C#, Blazor, Angular, React, Python and SQL
