I worked with Sara-Jayne for several months on a project for a charity, and I was extremely impressed both by her technical skills, and by her ability to understand the issues behind a question. Several times, I asked her if A or B might be possible, and I always received really helpful, insightful responses, which often went beyond the original question and showed deep understanding of what was actually needed. I have absolutely no reservations in recommending Sara-Jayne - she is brilliant.
