    I have over 27 years of software development experience, 21 of those using .NET technologies. I prefer projects in C#, however I also work with VB.NET. I am proficient in desktop (WPF/WinForms) and web development (ASP.NET MVC/WebForms) using .NET technologies. My other experiences include C++, SQL Server, SSRS/SSIS, XML/XSLT, ColdFusion, JavaScript, HTML5, WordPress, and Python. As a freelancer I pride myself on delivering a quality product on time and on budget. My Upwork profile is "top rated" with a 100% success rate. I do have a full time job that limits my availability for freelancing, up to 20 hours a week in the evenings and weekends.
