# Patrick Colm Audley

*Hacker · Full-Spectrum Technologist · Polymath*

A seasoned technologist with thirty years of international startup experience
and a broad palette of scientific, business and computing skills. Currently
splits time between [Blackcat Informatics® Inc.](https://blackcatinformatics.ca/) — the consultancy
he's run since 1996 — and applied research at the intersection of topological
data analysis, manifold learning, and large-language-model semantics.

## Currently

- Helping organisations shape AI and large-data strategies through the current
  technology inflection
- Researching emergent semantic-graph relations in high-order vector spaces
- Building [coding-ethos](https://github.com/paudley/coding-ethos): policy-as-code
  for AI coding agents

## Featured open source

- **[coding-ethos](https://github.com/paudley/coding-ethos)** (Go) — Policy-as-code enforcement for AI coding agents. MCP server + CEL policies + git hooks + SARIF + static-analysis guardrails so an autonomous agent can't ship code that fails your team's standards.
- **[nonlinear-semantic-graphs](https://github.com/paudley/nonlinear-semantic-graphs)** (Python) — Discovering emergent knowledge-graph relations in high-order semantic vector spaces — manifold learning + spectral analysis applied to LLM embeddings to surface relations that aren't explicit in the source corpus.
- **[ai-notes](https://github.com/paudley/ai-notes)** (Shell) — Working notebook for local-model experimentation, ML papers worth tracking, and small reusable bits of inference plumbing. Public so the notes serve as their own changelog.
- **[lru_cache](https://github.com/paudley/lru_cache)** (C++) — Fast, thread-safe Least-Recently-Used cache as a C++ template, with a comprehensive unit-test suite. First written in 2004 and still useful — the kind of small library that just needs to work.
