I build odd, useful things
and then measure them honestly.

RockID

Point your phone at a rock. Get a geologist's walkthrough.

You take a photo and a vision model finds the features: the grain texture, the rusty iron staining, the dark mineral streaks along hairline cracks. Each one comes back as a box on the photo. The app then gives you a guided tour, flying the camera to each feature in turn with an explanation underneath.

• Where you found it matters. GPS is read from the photo, reverse-geocoded, and turned into local bedrock context: native stone, glacial erratic, or beach cobble carried in.
• Built for bad signal. Identification runs as a server-side job. The phone can lock, switch apps or lose the network and the answer still arrives, with cancel and one-tap retry.
• The zoom maths is tested off-device: 4,530 assertions across screen sizes, photo shapes and feature positions.

Sparky

An Android app that gives a coding AI agent a phone.

Sparky connects over SSH to an AI agent running on my server. I talk to it by voice or text, and it writes code, builds Android apps and runs the servers. It talks back through the app:

• an Install button appears when it has built an APK
• generated images show up right in the chat
• when it needs a decision it asks with push-notification buttons, then keeps working
• a Control screen arms and disarms autopilot jobs (outreach, social, video), and a nightly Dreams run pitches new projects for a thumbs-up

If I send a message while it's still working, Sparky stops the job cleanly and merges the two requests. Several of the other projects on this page were built mostly from Sparky.

BeachBook + Satellite Reports

A crowd-sourced ground truth for coastlines, checked from orbit.

A Flutter app where people document beaches: sand, driftwood, flora and wildlife across 30+ metrics. Cloud Functions merge everyone's entries into one agreed profile per beach, shown as heatmaps.

Behind it, a paid report service pulls Sentinel-2 imagery through STAC, adds NOAA charts, and emails a finished report. A photo plant-ID endpoint runs on the same box.

Saver Ferry Planner

The cheapest way around the BC coast, on live sailings.

A route planner over the BC Ferries network. It pulls live sailing times, merges two feeds that each leave out half the fields, and estimates Saver-fare tiers from departure time. It also handles the fare quirks, like free northbound legs where the fare is only collected on the way back. It will wait for a cheaper sailing, but only within a limit you set, so it won't strand you overnight to save four dollars.

And more on the same box

• Farm Reports: satellite crop health (NDVI/NDMI) with weekly emailed snapshots and Stripe billing.
• LottoLedger: an astrological number picker whose claims are publicly tested by Sky Ledger (see the Data Science tab).
• NewLiver: a "just moved here" app with a scraped local events feed.
• A private app store for sideloading my own APKs, plus a social media scheduler and a visitor analytics server.
