Founding Engineer
Hi, I'm Graham.
I build software that solves real problems.
I'm a software engineer focused on building clean, performant, and well-crafted products. Open to new roles and freelance projects.
About
I'm a software engineer who started out building independently, and now build full-stack products under CapyBearHug LLC. Our flagship product is Mastiff Defense, an AI compliance platform.
Outside of work I'm into golf, video games, F1, and sim racing. I like things with technical details.
Projects
Mastiff Defense
A multi-tenant SaaS compliance middleware for enterprise and ecommerce platforms. Screens AI chatbot inputs and outputs through a three-layer pipeline (keyword matching, policy snapshots, and semantic evaluation) to prevent sensitive data leaks and prompt injection attacks. Ships with a per-tenant policy editor and full audit logging via AWS S3.
Side Projects
Astrova
Space exploration RPG built in Phaser 3. A real-scale solar map of ~1,390 star systems across 135 layers, 23 grind-to-99 skills, 10-faction politics, and kinetic + missile + railgun combat — with server-authoritative multiplayer self-hosted on a Raspberry Pi.
Box-Box (Live tracking being validated at the next race)
Formula 1 dashboard with analytics across 75 years of historical data and a Time-to-Strike widget that estimates how many laps until any chaser catches their target. Live tracking (real-time gaps, tire strategy) is built but waiting on the next race to validate against real data.
