I am a programmer at Canonical, Ltd. There, I work on Ubuntu One, on a variety of code in Python, ObjC, PyObjC, and C/C++ (Qt). Previously, I was a researcher working in HPC and computer architecture, and thus used a motley variety of usually appropriate tools to get things done.
For TeX.stackexchange.com:
A longtime TeX user, I wrote and maintained BibDesk for Mac OS X from 2000 to about 2006. I still use it regularly.
However, I am not much of a {La}TeX expert.
