Why chosen
He sits where cloud security meets coding agents. He co-founded and led Indent, a startup built around time-bound, policy-based access to cloud infrastructure. In May 2024 he joined OpenAI, where he led the first version of Codex CLI, the open-source terminal agent. In May 2025 he announced its rewrite as a native Rust binary with tighter sandboxing, and he has spoken on keeping code-executing agents safe. The agent in your terminal had a security-minded first author.
