Michael Doornbos

I’m a builder. Software, hardware, businesses, airplanes, stories.

I spent twenty years in security and infrastructure – industrial control systems, SCADA, solar farms, the kinds of environments where you can’t just reboot and hope for the best. I built an OT security practice from scratch at Assurance Data, and before that I designed IoT systems that helped disabled veterans live independently.

I started writing code as a kid and never stopped. That early fluency shows up everywhere: in the security architecture, in the products I’ve shipped, in the way I debug things by going back to fundamentals. I’m as comfortable reading a serial protocol trace as I am standing on a stage at SXSW.

I run OffGlobe LLC, a service-disabled veteran-owned company building products at the intersection of security, accessibility, and independent technology. Current work includes assistive technology for blind and visually impaired users, and LoreKeeper, a platform for capturing family stories before they’re lost.

I write across three sites. imapenguin.com is retro computing and programming fundamentals – 6502 assembly, Commodore 64, the machines that taught a generation how computers actually work. milkcrunch.com covers modern software development and engineering culture. evadot.com is commercial spaceflight and the new space movement, with 280+ articles and 100+ podcast episodes since 2009.

I built an HP-16C programmer’s calculator app for iOS because I wanted my favorite calculator in my pocket. I’ve also written three novels.

I’m a Navy veteran, a private pilot with multi-engine and instrument ratings, and a HAM radio operator (N4LNX). I built a Zenith 750 Cruzer kit aircraft by hand. I collect vintage computers and occasionally make them do things their designers never intended.

I live in Western North Carolina.
