About

Kevin Anderson

I’m a software engineer in New York City. I build open-source tools for AI- and agent-assisted software engineering, and my work is increasingly focused on self-improving agents and post-training open-weight models.

Most of that work lives under Existential Birds:

  • Daydream — a code-review agent that records every run and projects it into SFT/RL datasets. docs · code
  • Amelia — a multi-agent orchestrator for long-horizon software tasks. docs · code
  • Beagle — the shared library of agent skills the other tools build on. docs · code
  • Osprey — a self-improving coding agent whose directed-search loop rewrites its own prompts and tool descriptions against a token-penalized benchmark reward (in progress). docs

I also build Shelfspace, and I work at Ro. Earlier roles:
