Summary

A technologist at heart who loves to work on new challenges and empower workforces with capabilities they didn't even know existed. My main interest in IT focuses on Cybersecurity. While I prefer hands on technical tasks, I have recently focused on implementing and maintaining management systems for frameworks such as ISO27001 & 9001.

I have gained a large amount of varied experience in my career so far, from working in large scale teams to being a one man team. I am always moving forward, looking for my next challenge.
