About

I'm a technology leader with long-standing experience as a hands-on software developer. Over the years I've gained experience in working with many different technologies, people, and cultures. In many different markets and in various different geographical locations. In my free time, you may find doing a variety of activities such as hiking, exercising, walking my dog, and working on my personal development and skills through books and pet projects, and online courses. Oh, and did I mention I'm currently studying a bachelor's in Computer Science at Goldsmith's University of London? It's never too late to learn, and you should never stop.
