Builder of
small things,
patient with the long ones.

Working in emergency management from Vancouver Island, with AI doing some of the heavy lifting. Evenings I roast espresso, tend fermentation vessels, and show up for the communities my family is part of. This is the workshop wall.

§ 01Work

After twenty-nine years in uniform, I serve as the CTO for Ally Emergency Management — helping organizations plan for, respond to, and recover from the days no one wants to think about. I lean on AI across the practice — to sharpen plans, pressure-test assumptions, and build training that actually sticks.

I spend my days at the seam where machine intelligence meets human readiness — plans, tabletop exercises, after-actions, and the AI tools that make all of that sharper. The work that matters is rarely glamorous, which suits me fine.

§ 02Coffee — roasting & espresso

Roasting on a 300g tabletop roaster — about a batch a Month. Pulling shots on a modified Gaggia running Gaggiamate for full pressure-profile control, with AI helping me read the curves and dial in better shots.

§ 03Brewing — cider, beer, wine

Mixed Garage: cider in the autumn from my own and neighbours’ apple trees, session pale ales through summer using hops grown at the side of the house, and the occasional country wine when the fruit gets aggressive. I keep batches small and the spreadsheets honest.

§ 04Service & volunteering

Twenty-nine years in uniform, retired June 2025. Service didn’t end with the uniform — three orgs, three different hats. Showing up beats grand gestures — I try to be useful to the people doing the heavy lifting.

Retired 14 June 2025 after twenty-nine years in uniform. The reason I show up the way I do for everything else — careful planning, quiet competence, getting the team home.

Heads-down on Maxwell, a personal assistant that wrangles my other software and admin work — first cut shipping soon.

Roasting through a sack of Ethiopian Guji and finally getting the espresso dial-in I want. The cider is doing its slow thing.
