I build secure authentication systems for banks and AI products for clinics.

A bit about how I got here

I studied Computer Engineering at the University of Waterloo (2016–2021), where co-op took me through mobile engineering at a digital-health startup, backend work at Fleet Complete, and a research role applying spectral imaging to water-quality analysis.

After graduating I co-founded SeedCI (YC candidate), building unsupervised-learning cyberattack detection, before moving into full-stack consulting at Avanade, shipping EV-charging features for Ford's FordPass app and automating cloud infrastructure that cut a client's costs by $1M a year.

Today I split my time between security, fraud, and identity & access management (IAM) engineering at EQ Bank, where I partner with the IAM team on a live SSO/Okta identity migration during the PC Financial and EQ Bank merger, help build the unified app, and ship WebAuthn passkey (passwordless) support on iOS. I also run LEYOXA, the operating layer connecting AI across a dental practice, alongside Praxis, a Realtime-API + ElevenLabs voice AI agent integrated into NexHealth's EHR, live with paying dental clinics across North America.

Take the scenic route.

A slightly unserious tour of the serious patterns behind the work: curiosity, systems, movement, shipping, and whatever is over the next hill.

Curiosity before credentials.

The route usually begins with a question that is slightly too interesting to leave alone. Better questions have been the most reliable compass.

Visit every waypoint to complete the route. Detours are encouraged; straight lines are mostly a presentation choice.

No detour selected. Suspiciously efficient.
Playable experiment · AI-copiloted lunar sim

Autonomy you can actually watch think.

A real-physics drone on a real lunar surface. Fly it by hand, or hand it to an AI that scans, targets, and narrates every decision live: what it's mining, why, and where it's headed next. Ten resource nodes, five buildable base tiers, one honest experiment in legible autonomy.

Fly it yourselfReal Rapier physics, keyboard or gamepad, a lunar surface with actual landing gear and contact forces, not a scripted flythrough.
Or hand it to the AIWatch it scan for resources, lock a target, fly out, mine, and return. Every decision shown as a beacon line and a live narration log, not a black box.
Build as you goTen crystal deposits fund five real base modules (a habitat dome, solar array, storage tank, perimeter lighting, a vehicle bay) that go up as you deliver.
The pattern, not the pitch

I take on hard challenges and build technical products.

Model. Serving infrastructure. Production monitoring. User-facing product. Most people specialize in one layer of that stack. This is what happens when the same person keeps getting handed all four, in security, real estate, healthcare, banking, and marketing, with no overlap between the industries at all.

Simulation + AI

During the PC Financial and EQ Bank merger, I partnered with the IAM team on a live identity migration to Okta (SSO, unified identity across two banking apps), helped build the unified app, and shipped WebAuthn passkey (passwordless) support on iOS.
