# Nathan Mapp

**Profile.** Controller at a global venture-capital and applied-technology firm.

**Role in the source.** A second flagship example of a [[concept-judgment-architect|judgment architect]]. He codified over a dozen years of finance expertise into a series of markdown files referenced in real time by agents built on [[entity-claude-d27|Claude and Claude Code]]. This lets a team of two perform the work of ten, applying top-tier accounting judgment consistently across tasks.

**Attributed contributions in this vault.** The concrete markdown-codification practice behind [[action-codify-into-markdown]], the prerequisite it depends on ([[prereq-llm-context-windows]]), and a primary demonstration of [[concept-judgment-architect]].
