Update 29 June 2015 : I've accepted a full-time appointment from the Open Education Resource Foundation (the folks behind WikiEducator and OERu - the Open Education Resource universitas) to take up the role of Open Source Technologist. I'm chuffed to be joining them as the role seems like a great fit, and the team is very impressive! Many thanks to all of you who contacted me regarding opportunities.
To help folks understand what I do, I wrote this description of how we're working to democratise higher education . This is what I do from day to day .
These days I also maintain a technology blog that provides overviews of stuff I'm working on and specialised how-tos to help you implement some of the open source solutions I work with every day!
