I have more than 10 years commercial experience designing and implementing small to medium sized applications in C++, C# and Perl. Projects that I've spent the majority of time working on are: Database-driven Web Applications: Using Apache, Perl, mod_perl and the Catalyst Framework which are typically backed by a database such as MySQL, PostgreSQL and Oracle. C++/C# applications: I've developed applications under both Windows and Unix/Linux. Windows applications include both Console and Winforms apps using Microsoft Visual Studio.
