Multiple customers including a banking sector software vendor (STX Next Ltd.), government institutions (i.e. The State Forests National Forest Holding), academic institutions (Adam Mickiewicz University, Poznań, Poland). The contracts usually prohibit naming the projects as I’m mostly a subcontractor.

Technologies used: mostly Python 2.5+ (including Pylons, Django, Plone), C used for external library interaction and performance optimisation, continuous integration using Hudson and buildbot, source versioning through git and Mercurial (on customer is still using a massive CVS repository)
