As the web evolved in the late '90s, I grew alongside it, constantly learning and honing my skills. I later pursued a degree in Law at the University of Michigan while continuing to expand my business and technology knowledge through late-night coding sessions. From the beginning of my career, I have been primarily focused on the Microsoft stack. I started with classic ASP and quickly became an evangelist for the then-emerging .NET Framework for the US Department of Defense in 2000. Since then, I have made it a priority to stay on the cutting edge of technology, with a keen interest in ASP.NET Core 3, which I wrote about on the day of its release. Fast forward to the current day & I'm testing the .NET 10 previews for Microsoft. Feel free to contact me, and I'll gladly share my insights. In 1997, I began my consulting career, collaborating with esteemed organizations such as the US Department of Defense, SC Department of Transportation, eBay, State Farm Insurance, Verizon, GTE, Sterilite, and more. In 2005, I established coderPro.net and currently split my time between Chicago, Ecuador, and Prague, depending on the occasion. Main Specialties [in alphabetical order]: Access, AJAX, ASP, ASP.Net Core, ASP.net, ASP.Net MVC, BizTalk, Blazor, C#, ColdFusion, DJANGO, DNN, Excel, Flask, HTML, Information Architecture, JavaScript, jQuery, jQuery-UI, Kendo, Kentico, MAUI, PHP, POP3, project management, Python, Server Administration, SignalR, SMTP, Software Architecture, SQL, Tech Writing, Telerik, Travel Writing, Umbraco (4 - current), VBA, VB, VB.Net, VB6, Visual Studio Extension (VSIX) Development, WinForms, WPF "It is not the critic who counts; not the man who points out how the strong man stumbles or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again; but who does actually strive to do the deeds; who knows great enthusiasms, the great devotions; who spends himself in a worthy cause; who at the best knows, in the end, the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who neither know victory nor defeat." -- Theodore Roosevelt 收起
