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.
