Hi. I'm Mark. I've been developing awesome things with embedded software for 15 years and I help other people do the same. I've worked on self-guided lawnmowers, automotive electronics, color measurement devices, bluetooth beacons, and much more. I'm one of the creators of the open source tools Unity and CMock, which help people test C code. I'm one of the founders of Throw The Switch, an online community dedicated to making embedded software better.
