Smart Contract Engineer, building AI-powered security tooling for blockchain and AI-generated code

About

I write smart contracts and build the systems that secure them. Recent work spans GNN-based exploit detection for on-chain contracts, multi-agent auditing for AI-generated code, and applying LLMs to CSU Sacramento accessibility problems. I'm also exploring applied math and zero-knowledge, and when I'm not shipping code I'm making tech house.
