I'm a technology professional who's been passionate about computers since my Grandad introduced me to an Intel 386 back in the 90s when I was a kid. Those moments inspired a passion within for technology, and I've been playing around with anything with a circuit board ever since. Whenever I have a moment you can probably find me working on something computer-related, and this is where I like to write about those moments.
