01 — What we do
Mobile, web, security research and embedded hardware — built end to end, in-house.
What we do
Every service is run the same way: seriously, to production, and with the security hat on. If a build needs a hostile review, firmware, or a backend, it's all in-house.
Full product delivery — not just a repo. We scope, design, build and deploy web apps, PWAs and mobile experiences that people actually keep using.
Recent: BCW Mobile — installable, offline-first donation & dispatch app for a street-outreach crew.
We find the cracks before the market does. Offensive engagements, infrastructure and web penetration testing, and deep crypto / seed-recovery research — with findings you can act on.
Recent: seed-recovery & vulnerability research tools shipped as public projects.
From schematic to shipping firmware. Bespoke embedded systems on ESP32-class silicon with polished touch UIs, distributed node devices, and hardware-software integration that just works.
Recent: CODEPET — an AI digital pet on the Waveshare ESP32-S3 Touch AMOLED.
Senior hands without a permanent seat. Architecture reviews, codebase rescues, CI/CD and infrastructure, and the occasional impossible integration. Tell us where it hurts.
Hourly, sprint-by-sprint, or outcome-based — sized to your budget.
02 — Proof
Shipped products, open-source tooling and live security infrastructure.
Featured work
Not templates, not mockups — these are deployed products with live URLs, real brands, automated tests and working backends.
Decentralized Privacy Platform
A privacy platform that finds where your data lives on the web and helps you remove it — run by a decentralized network of encrypted crawler nodes secured on-chain. Powered by a custom PoA blockchain and a two-token economy.

Continuous attack-surface monitoring as a subscription
A hosted monitoring service that re-reads a domain's public footprint every day — Certificate Transparency logs, public DNS, the TLS handshake and ordinary HTTP headers — and emails you the moment any of it changes. Free scan first, $19/month to keep watching.

Offline-first directory of the services you need to actually reach
A directory of the services someone on the street in Saskatoon actually needs to reach — crisis, shelter, food, health, harm reduction, legal — built for the case where your phone has no bars and you need a number, not a website. The whole directory ships inside the app and works with the radio off.

03 — How
Small senior teams, working software, and no hand-offs to the void.
How we work
A small, senior team working directly with you. No account managers, no hand-offs — the people you meet build your product.
01
We listen hard — requirements, threats, constraints. You get a crisp spec and a fixed price before a line of code ships.
02
Architecture and UX on paper and in code. You see something walkable within days, not months.
03
Production code with the security hat on. Tests, review, and pentest-worthy hygiene from day one.
04
Deployed to your domain or ours. Monitored, documented, handed over clean — with retainer support if you want it.
Every deliverable ships with a hardening and review pass — as much because we'd want it done to us as because it's the right engineering.
04 — Engagement
Fixed scope, transparent rates, and a commercial model that scales with you.
