Hi, I'm Kevin. I work at OpenAI on codex and 🦞

Before this, I founded Dendron (YC W21) - a tool to help humans manage context (think cursor but for markdown files). This was based on my own problem of trying to manage my corpus of +30K markdown notes.

Prior to Dendron, I worked at AWS scaling load balancers and doing various 0-1 projects.

• 🔁 loops - Lightweight task runner that picks up ready work from GitHub Projects and drives tasks through an inner Codex loop.
• 🧩 skillz - CLI for managing Claude-style SKILL.md directories and syncing them into agent-readable workspace targets.
