McAllister
Electrical engineer and product developer.
I work on hardware, software, and embedded systems. Outside work, I enjoy experimenting with radios and spending time in the mountains.

01 / Work
From an idea
to a working product.
I’m an electrical and software engineer with more than 20 years of experience developing products, from unmanned aircraft to multispectral cameras. I’ve led engineering teams and businesses, and I still enjoy the hands-on work of designing, prototyping, and debugging.
I co-founded MicaSense and served as CTO, helping build its cameras and software for agricultural remote sensing. Before that, I spent nearly a decade at AeroVironment working on unmanned aircraft systems.
Today I develop worldwide data networks and run Inverted Labs. I consult on product development in electronics, firmware, and software, and make hardware for amateur radio.
02 / Beyond work
Amateur radio
and time outdoors.
Amateur radio
I’m K5EM and enjoy DXing, contesting, satellites, and antenna projects. I created SatMatch to help operators plan satellite contacts, and help bring SotaCAT hardware to fellow portable operators.
I also serve on the Western Washington DX Club board and manage the Salmon Run, Washington’s annual QSO party.
Getting outside
Hiking, mountain biking, skiing, and snowshoeing are all good ways to spend a day. A small radio and a wire antenna often come along for Summits on the Air or Parks on the Air.
I enjoy time outdoors with my family, including Scouting trips with my son. A quiet spot away from the city’s radio noise is a nice bonus.
