Donald B. Havery

30 years moving fuel across continents built the systems thinking. Now I build the AI infrastructure that makes complex operations intelligent.

60K+ lines of code across 15 repositories. Open to opportunities.

About

I design and build the orchestration layer between raw LLMs and useful products — agent runtimes, LLM gateways, voice pipelines, and the infrastructure that makes AI systems reliable in production.

30 years and 3.5M+ miles in transportation operations built the systems thinking. 60K+ lines of code across 15 repositories turned it into software. I work across the full stack — Python, React, TypeScript, FastAPI — with deep focus on multi-agent coordination, LLM routing, and real-time pipelines.

Currently seeking roles in AI orchestration, agent infrastructure, and production AI systems.
