Developer, UK. Mostly .NET/Windows stack with interleavings of open-source where it makes sense (it more often does than not ;-) ).
Also sysadmin/devop on regular basis for build automation, continuous integration, development infrastructure. Various experience capacity/load testing, both routine and as a result of things going bump.
Aware of life outside the IDE ;-)
