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".

I'm currently working on a project involving a chatbot and using artificial intelligence to allow customers to manage appointments over Amazon Alexa and Google Home devices. I consider my work ethic and communication skills to be my most outstanding traits, but I also have the experience to produce maintainable code and provide good estimates and meet them. I enjoy solving problems that others haven't yet but don't mind using my experience to avoid reinventing the wheel if a ready solution exists. I work hard to make my projects as simple as possible since simple code is easier to maintain and more accessible for others to understand. I've worked in the banking, retirement planning, mortgage, and security industries, and I have experience with compliance standards like HIPPA and PCI.
