I have spent 20 or 30 years working with all kinds of computer tech I could get my hands on. From big machines back in the 90s down to little shiny phones you hold in your hand nowadays. Writing iOS since pretty much the first iPhones, my day job is Swift fanatic with a dash of objective C and a side interest in "IoT". I'm currently working at a start up specialising in high tech IoT projects. And Arduino and Pi have been my side interest for ages. Half my flat is connected to one prototype or another.
