Heriberto Lugo
United States United States
Applications Developer for a very cool company in Connecticut which is one of the top 5 Amazon sellers. Currently using C# (web and desktop) and SilverLight/LightSwitch.

Self taught programmer. I have been learning programming since 2001. Began with HTML, CSS, JavaScript during the days of the browser wars with Netscape's layer tag. I Started learning Perl, then Java. Couldn't get to far with Java because NetBeans always froze my Windows ME machine after a few minutes. Since then I have learned C++, VB.Net, C# (winforms, aspx and SilverLight/LightSwitch), php (core, Drupal theming and WorpPress plugins/widgets), MySQL, T-SQL, and SQLite.

I still create webpages, and do my own graphics, but prefer working on desktop applications. I spend my free time working on desktop projects, or helping beginners where I can in forums.

I worked for a short period as a web developer and pc hardware technician. During which I learned the basics of networking and a small amount of server admin (including running multiple virtual windows to act as dummy machines for workstations using dedicated lan ports with dedicated ip addresses..

Most of my professional experience however has been in the automotive field. I began working in automotive after about 1 year after I found my interest in IT. I was using my work to pay for bills while I attended college for graphic design. Eventually went to school for programming, but only survived for 2 semesters, paying upfront for the classes was to much to handle so I once again had to stop my schooling.

I have been programming in VB/VB .NET and Windows for a very long time.

I have been programming, in general, for a very very long time.

Started in C/C++ under DOS (when I was 10, in 1986!). I even wrote a FOSSIL driver in assembly (for those of you who remember what a FOSSIL is, you're a fossil, I'm a fossil)... so I got a book that taught me serial port interrupt driven communications routines in C and ASM. Then I moved on to Pascal. Pascal disappeared and became unavailable to my youth and poorness (when it became Delphi).

Moved on to VB 6, from VB 6 I discovered the Windows API and, in fact, I am developing an ever more exhaustive port of the Windows API into VB .NET.

(I recently just reinstalled my VB 6 compiler on my Windows 8.1 system. Windows 8.1 made several protests and at least one dialog box suggested I needed therapy, I think ... but it still ran, and compiled! I use it mainly to reference my ancient projects to slowly port them into .NET ... yes, still. )

Now, here I am, years later, still learning, still working with VB (and to a lesser extent C# and to an even lesser extent C++).

I've been concentrating on getting good practice with WPF and WCF and all of the other neat Microsoft technologies of the current era.
