AI engineer, now at Brinker, who designs autonomous human-in-the-loop agent systems and production-grade RAG, and builds the full stack around them, from Postgres and Next.js to a shipped iOS app. I came up through marketing operations and taught myself to build with AI; one platform I built was acquired for six figures within weeks of launch. I work framework-free and evals-first, and I care about systems that actually run: fact-checked, measured, and reliable.

Projects

Personal RAG Knowledge System: Hybrid retrieval over my Obsidian knowledge graph (keyword + Pinecone / multilingual-e5 + wiki-link expansion) that surfaces the right notes into my agents and stays silent when unsure. Measured with a golden-set eval (Recall@4 ~0.91, MRR 0.80).

AI Recruitment Chatbot (2023): One of my first AI builds, right after the OpenAI API launched: an automated lead-qualification bot (OpenAI API + GoHighLevel) for Adrian College Rugby that converted 10 D1 recruits in two months.

Detroit Tradesmen RFC: Community rugby club website rebuilt with TypeScript; responsive design with team-management features.
