Hello! I'm a software engineer who builds infrastructure for AI agents. I currently maintain Termio, a terminal-first environment for agentic development, and OakReader, a native macOS research library for reading papers with AI.
Before that I worked on ACI.dev at Aipolabs. More in projects.
I write here to think out loud. Many posts are public drafts.
