About

From the firehouse, not just the keyboard.

I'm a serial entrepreneur with three decades of technology and business development behind me. I came to Washington State to work at LapLink, was Director of Engineering at Starwave, a Paul Allen company, and helped start Altrec, one of the first online direct-ship retailers for outdoor enthusiasts. Then I founded WhatCounts, an email publishing platform that grew for ten years without outside money and sold in 2010. I co-founded Eyejot, one of the first web-based asynchronous video communication platforms. I founded Spryly, a flexible digital contact card platform. And I'm a partner in FireTrex, which builds staffing, training and certification software for fire departments.

I'm also a volunteer firefighter and EMT with King County Fire District 27. That's where a lot of my recent work comes from: TapRate, NV Impact, Dwell Secure and the FireTrex apps were all shaped by calls, drills and the people who run them.

The rest of the time I build under the Spryly Labs banner: open-source tools like Hoster, MoveItHere and Claude Monitor, and public-interest guides like the AI Atlas and the PSE customer guide. If it can't be used with gloves on, in bright sun, at 3 a.m., it isn't done.

Most software is designed for the person who writes the check, not the person using it at 4 a.m. I try to build the opposite.How FireTrex describes itself, and a fair summary of everything here.
