Developer in scientific fields.

• My world is vertical market shrinkwrap. Do you know your world?
• VB6, VB.NET, C, Fortran, Perl, PHP...
• User interfaces, graphics, data manipulation, numerical models.
• Database stuff with Access/MySQL/SQL Server.
• Physics degree, little formal training in development

In my young days I used to write things like compilers and chess programs for fun - but that was last millenium :)
