Chris Berry

Engineer at OpenAI working on systems that help researchers move faster and scale training.

I build small, terminal-first tools for real-world systems: commands that are composable, explicit about state, careful around physical writes, and useful to humans and agents alike.

Control tools

Project System Read surface Guarded write surface
gatectl LiftMaster/MyQ accounts, devices, online and open/closed state gate and garage-door open/close
poolctl Pentair ScreenLogic controller, bodies, circuits, pumps, cleaner, delays cleaner on/off and delay cancel
hottubctl Sundance SmartTub spas, connectivity, water/set temperature, freshness target temperature
switchctl Local switch backends named endpoints, roles, reachability, readiness on/off and enable/disable

The *ctl projects share the same shape: private configuration, compact human output, safe JSON for automation, explicit confirmation for mutations, post- write readback, hardware-free tests, a language-neutral script/install contract, and honest reporting when an integration is uncertain.

Engineering interests

  • systems and infrastructure
  • local-first and terminal-first software
  • practical home automation
  • agent-driven workflows
  • C, C++, Python, and Rust
