# Wes McKinney

Software engineer and open-source creator (creator of `pandas`, co-founder of POSIT, Arrow contributor). In 2026, McKinney pioneered high-volume agentic engineering architectures, operating autonomous coding agents across multiple parallel projects generating ~1M lines of code over 6 months at 1.3–1.4B tokens/day.

## Agentic Engineering Philosophy

McKinney contrasts "vibe coding" with disciplined agentic engineering:
> "The difference between vibe coding and agentic engineering is planning, architecture, and caring about the output." [[source: hugo-bowne-anderson-agentic-software-factory-2026]](/wiki/raw/articles/hugo-bowne-anderson-agentic-software-factory-2026)

When code production outpaces human review capacity, the human role shifts from reading diffs to defining architectural boundaries, managing task decomposition, and supervising automated review harnesses.

## Toolchain & Harness Innovations

- **RoboRev:** An automated daemon running as a post-commit hook that triggers high-reasoning LLM code review on every commit, maintaining an append-only findings ledger.
- **Commit-Every-Turn Discipline:** Enforcing granular git commits at every agent step to maintain review ledger precision.
- **Local Control Plane:** Kata (local issue tracking), Middleman (local PR review dashboard), and Agents View (session retrieval across hundreds of agent traces).
