Gareth has been coding since he got a ZX81 when he was eight. Back then, you typed in the games you wanted to play, so you really needed to earn your Moon Lander game. But gaming didn't stick, and instead, Gareth created systems, which he has continued to develop to this day. With a passion for making things, he loves to take each file he touches to the next level. An energetic self-starter, Gareth is an inventor who is always brimming with ideas to deliver quality solutions.
