## About

Aaron Chartier is a technologist working on agent orchestration, context engineering, and GenAI infrastructure and security — the unglamorous discipline of getting AI agents to do real work reliably.

His path runs from helpdesk through IT operations and process engineering into AI leadership: sixteen years in technology, the last several leading applied-AI work in a large enterprise. The operational background is the edge — he understood how enterprise systems actually break long before he started writing specifications for agents that take instructions literally.

His throughline is specification precision: vague intent is what makes agents fail in production, and writing a spec an agent can execute reliably is a learnable, teachable discipline. He pair-codes with agents — he specifies, the agent writes, he reviews for correctness and safety — evaluates and integrates the surrounding stack (Langfuse, LiteLLM, n8n, Azure OpenAI), and mentors developers from their first prompt to production agents.

He builds tools designed to be driven by agents — inkjet, a set of agent-first command-line tools, and this site, which is built to be read by machines as well as people.
