Built on my own time
Jenny — Autonomous AI Agent
A single-tenant autonomous AI agent running as a permanent systemd service. Multi-provider LLM routing across 7 model tiers, 4-layer cognitive memory architecture, 80+ auto-discovered tools, structured approval gates, and a 15-job automation scheduler. Built to compound in value over time — the memory pipeline turns conversations into searchable long-term knowledge.
Students build AI knowledge bases from scratch — teaching facts, defining rules, and shaping an AI's understanding. Automated evaluation via AI-conducted interviews tests true comprehension, not memorization. Analytics dashboards, COPPA compliance, and content moderation built in. Based on the principle that the best way to learn is to teach.
2D Game Engine
End-to-end game engine with frame-independent game loop, entity-component architecture, collision detection, sprite-based animation systems, and input management — all built from first principles.
How I think about systems
Systems Over Features
I architect platforms that compound in value — not one-off features that decay. Every system I build is designed to make the next system easier to build.
Optimize for the 2AM Problem
If it breaks at 2AM, it should fix itself. Resiliency patterns, circuit breakers, and graceful degradation aren't nice-to-haves — they're the architecture.
Make Others Dangerous
The highest-leverage thing a Principal can do is multiply the capability of every engineer around them. Guilds, patterns, and shared libraries are my force multipliers.
Let's build something.
Open to strategic opportunities where architecture, AI, and engineering leadership converge.
