Career Journey
Founding Engineer (#001)
Energy Sector Startup · 2018 – 2022
- •First hire. Built everything technical.
- •Zero-trust platform: dozens of portals → one mobile app
- •Migrated systems with 12+ years uptime
- •Ansible automation: deployments went hours → minutes
Belize (2008–2012)
Missionary kid with a computer. Built whatever people needed.
- •First paying job at 14 — Dreamweaver, Drupal, Joomla
- •Jailbroke iPhones, rewrote PRLs for CDMA models
- •Facebook-driven mobile ordering for local restaurants
- •Watched every Apple keynote on Engadget in the background
Apple (2013–2017)
Got paid to do what I'd been doing for free since I was 14.
- •Top performer in Western Canada
- •ACiT + ACMT certified
- •Years later: invited to WWDC 2022 (1 of ~2,500 from 37M developers)
IT Consulting (2017–2018)
First time I got handed problems nobody else wanted to touch.
- •Azure AD migrations everyone avoided
- •Phishing susceptibility: 33% → near-zero
- •Closed tickets faster than SLA
Startup #001 (2018–2022)
First hire. Built everything technical from scratch.
- •Zero-trust platform: 80+ portals → one mobile app
- •Ansible automation: deployments went hours → minutes
- •On-call for mission-critical monitoring
Energy Sector (2022–2024)
Cloud infrastructure and OT software. Messy problems, real users.
- •First Kubernetes deployment at one company
- •FinOps: found six-figure annual savings
- •Took over an OT platform and made it something people use
UK (2024–Now)
Moved for adventure. Building AurorionTech. Looking for my team.
- •Built iOS app as sole engineer — pending release
- •Enterprise infra patterns on ARM hardware, near-zero cost
- •Looking for hard problems and good people
Why I do what I do
Someone says 'we've tried three times and it didn't work.' That's where I come in. I'll dig into it, ask the questions nobody asked yet, and keep going until something clicks.
I turn messy systems into things people actually use. 80 scattered portals became one app. A legacy platform nobody liked became something operators asked for by name. I like making complexity feel simple.
I ask a lot of questions. I draw diagrams. I write things down. When I leave a project, there's real documentation, not just code comments. I've been the person who inherited the mystery codebase. I don't do that to people.
I argue about architecture. I celebrate small wins. I occasionally send diagrams at midnight. The best work happens with people who care about their craft, and I try to be one of those people.
Problems I've Solved
80 Portals Nobody Could Navigate
Field operators were juggling 80+ bookmarks across legacy systems. I built one mobile app that replaced all of them. Air-gapped, zero-trust, actually got used.
An iOS App for Discovering History
Walk to a location, discover a historical figure, have a voice conversation. I built everything — the iOS app, the API, the infrastructure. v1.0 pending App Store release.
Enterprise Patterns, Zero Cloud Bill
Took the same patterns I used on enterprise Azure — container registry, CI/CD, mesh VPN, monitoring — and ran them on ARM hardware in my flat. Proves the architecture scales in both directions.
AurorionTech
What happens when you give me 6 months and a problem nobody's solved
Aurorion is an iOS app that lets you have voice conversations with historical figures. Walk down Edinburgh's Royal Mile and talk to David Hume about philosophy. Stand outside Holyrood and ask Mary Queen of Scots what it was like. The app knows where you are, surfaces the right characters, and streams real-time voice — speech recognition, GPT-4, voice synthesis — so it feels like an actual conversation. I built everything: the iOS app, the API, the infrastructure. v1.0 is pending App Store release.
- v1.0 built with voice conversations
- 49 repos → 1 monorepo
- API moved to Cloudflare Workers
- H3 geospatial for discovery
- Self-hosted on ARM64
- 1,411 commits with Claude Code

Got a hard problem?
UK
I'm looking for a team that has something messy to untangle. Legacy systems, scattered tools, problems nobody's figured out how to start. I'll dig in, ask the hard questions, and build something people actually use.
