Demonstrated work experience

Anyone can list technologies. This page is the things you can actually click — a multiplayer game running in production, interactive pieces built for real businesses, and sales-showroom software from 2007 that I've brought back to life in the browser.

Everything on this page runs on your device. Nothing here is a mockup — if something breaks, it is breaking for real.

Playable right now

Fifteen Two

2026 · live in production

A full cribbage game for the web — no app, no install, phone or TV. It plays single player against an AI opponent that computes exact expected value over all forty-six possible starters, head-to-head against another human, or as a two-to-eight player party round where everyone gets the identical deal and races to count it correctly.

The rules engine was verified against independent reference scorers across 300,000 hands and 884,000 pegging positions with zero mismatches, then fifty-six complete games were auto-played through the real interface. Multiplayer runs over WebSockets with server-authoritative scoring, and a dropped phone reattaches to the same seat holding the same cards instead of killing the table for everyone else.

The Fifteen Two opening screen: a dark green felt board with the game's rules and buttons to play the Captain, host a table, join a table, or open the trophy room.
Fifteen Two — head-to-head against the Captain, or a table of up to eight.

Wheel of Doom

2026 · staff prize draw

An elimination wheel for a moving company's crew draw, shown here under my own demonstration branding. Staff earn tickets, and the wheel spins people out until one survivor is left — so tickets have to buy safety, weighting the odds by the inverse of the ticket count rather than by the count itself.

The reason it isn't simply one wedge per ticket: a crew member with three hundred tickets would turn the wheel into confetti. Small piece, one real design problem, and it runs on the warehouse TV on draw day. Add a few names and spin it.

The prize wheel before a draw: a dark screen with an empty teal wheel waiting for entrants, and a panel on the left for adding each person and the number of tickets they carry.
Waiting for entrants — add names and ticket counts on the left and the wheel builds itself.

Booking sites, unbranded

Three complete booking sites for small coastal accommodation — a pair of cottages, an island guest house, and a harbourfront inn. Each one is a working front end: pick dates, see what is free, get a price, and book, on a phone, without a phone call.

These began as speculative builds — made to show an owner what their site could be, rather than commissioned. So the businesses they were built for are not named here. Every name, photograph caption, phone number, address and place has been replaced with a placeholder, and each page carries a banner saying it is a demonstration. The design and the engineering are mine to show; the identities are not.

Two cottages on a beach

2026 · booking front end

The problem in one line: the real site had no way to see whether a date was free, so every enquiry became an email. This turns that into a calendar — availability, a nightly rate that changes by season, minimum stays, and a total before you commit.

Dates and guests up front, because that is the only question a guest has.

An island guest house

2026 · booking plus a local guide

Same booking core, different job around it. A guest house on an island sells the island as much as the room, so this one carries a what-to-do section alongside the calendar — charters, kayaks, trails, the ferry.

The operators listed in that section are real businesses in the original. They are genericised here, because a third party's name and phone number should not appear on my portfolio to make my layout look populated.

Rail & Sail Montessori House

2026 · Richmond, BC · live

A Montessori school's curriculum, staff biographies and registration material existed as a folder of Word documents. This is that folder turned into eight pages a parent can read on a phone while deciding where to send their child.

Statically exported, so there is no server to patch and nothing to fall over on a Sunday, and deployed onto S3 behind CloudFront on Route 53 — the school owns the infrastructure rather than renting another monthly subscription.

The Rail and Sail Montessori House home page: the school's lighthouse logo above a painted banner of five children looking out to sea, with the welcome headline over it.
railandsailmh.ca — eight pages, no server, served from the edge.

Rich Rock Resources

c. 2008–2016 · still up

A junior exploration company's public site — management, properties, corporate filings, and the NI 43-101 technical reports an investor actually turns up to read. Built alongside the investor CRM, tax issuance, and shareholder communication system behind it.

Its two sister companies are gone: Metal Mountain stopped answering, and Eagle Peak's domain lapsed to a broker. This one has been serving continuously for the better part of two decades without me touching it.

Experience Engines — the showroom touchscreens

Between 2007 and 2008 I built "Experience Engines" for luxury property sales showrooms: floor-to-ceiling touchscreens a buyer walked up to and used unaided. Three of them survive — Horizon in Vancouver, Koloa Landing on Kauai, Indigo in Osoyoos — and together they run to about 758 MB, most of it video and panoramic walkthroughs that mean nothing outside the original kiosk. What follows are the modules that still stand on their own, running off the untouched original files.

Adobe killed Flash in 2020, which should have made nineteen years of this work unshowable. It plays here through a WebAssembly interpreter I host myself — no third-party requests, nothing rebuilt, nothing re-authored. Each one loads only when you ask for it; the stills below are what you get.

Horizon — interactive site plan

2007 · B3 Communications · still works

A buyer walked up, explored the development, opened a lot and saw whether it was still available. Pick one of the nine home designs down the left and the plan repaints every lot by whether that design fits it — compatible, compatible with modifications, or not at all. That is a real constraint solver behind a sales tool, in 2007, on a touchscreen.

The Horizon site plan: seventy-four numbered lots drawn along named streets, with a column of home-design buttons and a compatible / compatible-with-modifications / incompatible legend.
Seventy-four lots, nine home designs, filtered live against each other.

Indigo — view study

2008 · B3 Communications · still works

The question every buyer in a tower actually asks: what will I see out of my window? Choose a floor, then rotate through the compass, and the screen shows the real photographed view from that height and bearing over Osoyoos Lake. Shot floor by floor and stitched so the answer is evidence rather than a sales promise.

The Indigo view study: a panoramic photograph of Osoyoos Lake and the surrounding hills, with a floor selector reading Floor 07 and left and right arrows to rotate the view.

Koloa Landing — the vision

2008 · B3 Communications · still works

The opening module of the Kauai resort engine: the illustrated master rendering, with the copy panel over it and a toggle between the mountain and ocean aspects. This is the screen the buyer met first, so it had to load instantly and look like the brochure they were holding.

Flash, outside the showroom

Not everything from those years was a property kiosk. This one is a product, and it runs the same way — off the original file, through the same interpreter.

The pen — a product configurator

2006–2007 · banker's promotional gift · still works

Not a property this one. A bank was choosing an engraved pen to give clients, and needed to see it before ordering thousands. So: drag the slider and the pen turns through a full rendered rotation, press engrave to put the marking on the barrel, press zoom to get close enough to judge it.

This is the sort of thing the CV means by "3D product turnarounds" — rendered frame by frame, then wired to a scrubber so a buyer could inspect the object from any angle without a physical sample. Two decades before every retailer had a 3D viewer.

Drag to rotate, then engrave and zoom — the whole tool is that control bar.

Shown rather than run. This one carries its own 2007 preloader, written when a 2 MB download was a long wait, and it paces itself frame by frame rather than by how fast the bytes actually arrive. Under the modern interpreter that works out at roughly twenty minutes to reach the pen — so pressing a button here would only buy you a progress counter.

Recovered, but not playable

Two pieces built for CKNW in 2008. Both still render, but neither can be played: each pulled its questions and scores from a server that has been gone for years, so what survives is the shell. They are here as stills rather than buttons, because a "Run it" that leads to a broken screen is worse than a photograph.

Clicks for Kids — the CKNW Orphans' Fund poll

2008 · CKNW · charity

A weekly real estate poll where answering was the donation. One response per person per week, each one adding to the CKNW Orphans' Fund, with a thermometer tracking the total against a $20,000 target. Sponsored by PilotHouse, run on the radio station's audience.

The mechanism is the whole idea: make giving take one click, attach it to something people already wanted to do, and show them the total moving.

The PilotHouse Real Estate Poll: a dark red panel with a multiple-choice question card, the CKNW Orphans' Fund logo, and a fundraising thermometer running from zero to twenty thousand dollars.
The question text reads "undefined" — that content came from a feed that no longer exists. The frame, the charity mechanism and the thermometer are intact.

Test Your Real Estate IQ

2008 · CKNW · contest

A two-week quiz round with a live leaderboard — rank, name, location, score — and a $50 restaurant gift certificate drawn from the top scorers, ties broken by random draw. The last winner it ever recorded was Barbara Clendenning from Squamish.

The Test Your Real Estate IQ screen: a dark red panel with the contest rules down the left, an empty five-row leaderboard of rank, name, location and score, and a play button.
The leaderboard is empty because its scores lived on the server. Everything else is as it shipped.

Print, too — the whole span

The work has never been only screens. Long before a job meant a React Native app, it meant whatever the message needed — a kiosk, a website, or ink on paper. Print, web, native: one person who takes the whole thing from idea to the thing in someone’s hands, rather than three vendors and the gaps between them.

Cummins Western Canada — Dealer Support Manual
