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
Multiplayer space exploration RPG built in Phaser 3. 89 star systems across 57 layers, faction politics, and kinetic + missile + railgun combat. Self-hosted on a Raspberry Pi.
Box-Box
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.
