Joshua Mason — Applied Scientist & AI Engineer
I build agents for taxes, audit, and accounting at Thomson Reuters. My work spans RAG architectures, ReACT flows, agentic search, coding agents, OTEL observability, and sophisticated evaluation frameworks (including human-in-the-loop annotations) to ensure answer quality and structural guardrails. M.S. in Computer Science, NC State.
