INTP.
Been in the industry, actively developing some form of software, for 15 years.
Currently:
Rapid prototyping, creative coding, proving ideas and pushing limits.
Simplification.
Java, Python, Appengine, Javascript (yes jQuery, yes html5, etc etc),
d3js, interactive infographics, data viz (I have patents in this.)
Data Acquisition, NiDAQ exploration, some BioTech,
OpenGL, WebGL, libgdx,
Blender, 3D modeling, animating, shaders and cycles.
I used to write a lot of C#, and a lot of Sharepoint apps, workflow, even some ios. In fact, you might even find my name in some books.
These days I stick to what I love - having ideas and implementing them. When you can build anything from nothing, the creative consumes.
