Bio
Malcolm Turnbull
James is a very fast learner and is committed to picking up new skills, giving him a broad range of knowledge to draw from. This helped bridge the gap between development/coding of our software, and the end-users’ experience, as he was able to offer both network infrastructure advice, and provide/plan new features and fixes, often coding them himself. His excellent communication skills saw that he dealt with support cases efficiently (without being overly terse), which has been vital at times when there has been a spike in the number of incoming support cases. It was also to the benefit of the rest of the support team. I had no problem in having James work remotely at times, and this added a lot of flexibility to the team in terms of support-hours.

James is a great guy to work with. He puts a lot of effort and energy into everything he does and quickly masters new and challenging concepts. He certainly mastered the support role and had significant knowledge of the inner workings of the system and the strategies they employed. I would happily work with James in the future.
