I am employed by Chevron Corp. as an Application Performance Analyst troubleshooting performance problemns involving enterprise applications. I love to program in C#, but I've programmed in many of the most popular languages.
My first programs starting in 1979 were written in Microsoft BASIC on a TRS-80 Model I computer with 4K ROM that mostly contained the code to run BASIC, and 4K RAM. I learned to program on that machine starting with BASIC, and going on to Z80 Assembly Langauge, C, and Pascal.
