Senior iOS Developer at 7/Apps (http://7apps.com)

For the web, it's Python and Django or Google App Engine.

For databases, it's Core Data these days. But I'm also proficient in MySql, Sqlite, MS SQL.

For SCM, it's Git and SVN. Git and GitHub make me so happy!

I've also been paid to write C#/ASP.NET and PHP, but have mostly forgotten those days.
