About Me

I'm a career changer that worked for many years as a biologist and research scientist before moving into a management job that involved some web development.

Now I've been bitten by the development bug, which has led me to acquire many new skills; but I feel an unquenchable thirst to learn more.

I've now found an opportunity to apply and expand my skills and experience in a full time web developer role within the Higher Education sector.
