I started as a FORTRAN programmer, paid my dues writing C and X11/Motif, switched to Perl, discovered Tk, and from that, Tcl, and spent the next decade plus writing cross-platform GUIs in Tcl/Tk.
I then spent three years using python and a smattering of ruby to create a cross-platform automated testing framework. After that I had two more gigs in windows shows, building automated testing frameworks and leading automation teams. I am now back to being a python developer at a small company in the independent publishing business.
I was profiled as python developer of the week at http://www.blog.pythonlibrary.org/2015/03/02/pydev-of-the-week-bryan-oakley/
The open source projects I currently am active on are:
I also maintain a sporadically-updated blog at boakley.github.io, focused mainly on my work with the robot framework.
