Josh McKinney
Software engineer: backend, platform, security, developer tools.
I build the systems other engineers depend on: authentication and authorization services at Amazon and AWS, AI developer tooling on OpenAI's Codex, and Ratatui, the Rust terminal UI library I co-maintain. I care about clear interfaces, good docs, and tools that are straightforward to operate.
