I build the systems that make AI agents work.

14 years of software engineering. Production agent harness on Anthropic Claude. Building the infrastructure that keeps AI agents reliable, autonomous, and on track.

What I do

AI agents are powerful. Without a harness, they're unreliable. An agent harness is the infrastructure layer between an AI model and the real world. It decides which tools an agent can use, how sub-agents are spawned and supervised, how context survives across long-running sessions, and what happens when something breaks.

Harness
The model is the brain. The harness is everything else — task decomposition, tool governance, state management, failure recovery, evaluation loops. It's what turns a language model into a reliable production system.

Selected work

  1. 01

    Agent Harness on Claude

    APSU AI · 2024 – Present

    Production multi-agent orchestration with sub-agent spawning, tool governance pipeline, and contract-based task delegation. Cron-driven autonomous executor for 20+ scheduled workflows with self-healing error recovery. Multi-model routing across Claude, GPT, and Gemini with provider failover.

Harness Engineering: Why the Same Model Works for Others But Not for You

From Prompt Engineering to Context Engineering to Harness Engineering — AI engineering has gone through three fundamental shifts. What determines whether an agent can reliably deliver isn't the model itself. It's the runtime system around it.
