Mark Tearle is a Senior Software Engineer at QCIF at QCIF. He possess expertise in perl, python, linux, php, system administration and 39 more skills. Colleagues describe him as "Mark is an expert on all things networking, infrastructure and system administration. I've known him for many years and seen him deliver some excellent talks on the topics which demonstrate his depth of knowledge but also his ability to relay information to people such as myself who usually work higher up the stack." and "Having worked closely with Mark while stationed at the Faculty of Arts, Humanities and Social Sciences, I developed an appreciation for the very difficult job Mark holds trying to please many masters. Upon taking a contract to do Mark's role while he was seconded to write fibre documentation on a more full time basis, I have developed an even greater respect for Mark's ability to work on, at times, up to 30-40 different projects at once ranging from bollard and call post installations, right through to ensuring close collaboration with consultants so major building projects were delivered with communications infrastructure that met client expectations. I would have no hesitation in recommending Mark to anyone looking for a dedicated and friendly individual who's encyclopedic knowledge of IT and communications equipment, standards and developments make him an incredibly valuable resource."
