Multi-Agent Claude Orchestration

Prefrontal Cortex Executive Function

Built a multi-agent workflow orchestration system using Claude Sonnet 4.5 for high-level planning and Claude Haiku 4.5 for fast execution tasks. Mirrors the prefrontal cortex executive function architecture: deliberate reasoning (Sonnet) handles strategic planning, task decomposition, and complex decision-making, while rapid execution (Haiku) processes routine operations, data transformations, and API calls.

Deployed LangGraph state machine with persistent workflow state across 15+ autonomous agents. Delivered in 6 weeks—client's previous vendor quoted 6 months. Claude Sonnet 4.5's 1M-token context window eliminated chunking for entire codebase analysis, processing 78,000 lines of Python across 340 files in single requests. Zero hallucinations on code references.
