A little background
About ZombieMutex
I'm Jeffrey Monica. ZombieMutex is my corner of the internet. I've built and worked on iOS, Android, backend, security and AI systems, including software used in enterprise environments. I like being close to the implementation and figuring out what actually happened when a request, release or integration goes sideways. A diagram can be beautiful and still be wrong.
But work is only part of life. I also care about dogs, animal welfare, the people around me, cooking, hiking, travel, photography, D&D, and following an interesting idea far enough to learn something new. This website gives all of that a home.
I started collecting project notes here because I wanted a place to show what I've built, explain my decisions, and meet other people who enjoy building things. It grew into a home for life outside work too. Some pages are technical; others are just things I care about.
On the technical side
Mobile apps, secure communications, backend APIs, device integrity, agent integrations, reverse engineering and reliability. Plenty of interesting mistakes along the way.

Food, the outdoors, new places, photography, reading, and whatever else turns into a story.

There's a longer profile if you want the engineering background: what I work on, how I debug, and why I care about getting the details right.
