I am a freelance developer, I work mostly with ASP.NET in C# and MS SQL SERVER. I also do some front-end stuff as well, i.e. HTML, CSS and JavaScript, including some libraries such as JQuery.
As a hobby I also develop games in Unity3d, some 2d and some 3d (none of which are released to the public as it is just a hobby)
I am also starting to experiment with 3D modelling in Blender, again this is another hobby skill.
