Photo of Niall Barr sitting at a desk. I am a software developer specialising in Learning Technology and Educational Interoperability specifications, in particular IMS QTI 2. My background is in Engineering and Life Sciences, and I have degrees in Aeronautical Engineering, Bioengineering and Natural Sciences, however I have been working as a Learning Technology Developer for almost 30 years. The majority of my development work is currently done in PHP and JavaScript, however I also do some programming in C#, C++, Python or Java when one of these languages is most appropriate.
