I've been programming for 30 years, 20 of them in a professional environment. I've worked on everything from small back-end ETL programs, to military embedded systems, to web front ends, to desktop applications, to operating systems. My experience ranges from the youngest startups to some of the largest banks, software and consulting institutions.
I've worked many different languages ranging from bare metal assembly all the way up to modern C#. These days I mainly concentrate on the Microsoft stack for backend work (along with open source databases), with the standard web front end technologies - HTML, CSS, JS, jQuery, Angular, Bootstrap, etc.
