about-me

About Me

Principal Engineer with 8 years across platform, DevOps, and full stack, now focused on agentic AI infrastructure. Built the MCP mesh connecting 250+ tools to every team at Accuris, run 100+ microservices across 6 regions on Kubernetes, and standardized deployments for 1,000+ repos. Former first engineering hire at an AI startup with a track record of working directly with clients to turn requirements into shipped product. Strongest at the intersection of customer problems, system design, and fast execution with agents.

Passion Projects

Projects I've built in my free time to solve personal needs or explore new technologies.

Sauce

Sauce

An agentic operating loop for Obsidian. Notes become node-based work graphs that agents like Claude Code and Codex execute in isolated workers, with scheduling, retries, handoffs between agents, and a persistent task store. Started as a loop-based forward deployment mechanism, rebuilt around graphs. Versioned vault platform shipped via Homebrew, MIT.
