Mark Roberts

I have broad experience in many fields, and I often use the knowledge gained in one field to advantage in the other. I believe it is important that any work I do is stable and use my experience to ensure that these objectives are met. I regard the fact that my work history covers a wide range of technologies and roles encourages me to achieve the best solution for the task in hand. I am skilled in a wide spectrum of development skills from database development, “Front End”, “Back End” to DevOps. I have appeared in the national press and BBC national radio concerning Internet security, and some university computer science courses and papers have been based on work I performed in my spare time.
