I build AI agent systems, developer tools, and real-time collaborative software.
I’m especially interested in making agentic software easier to operate in practice: explicit tool contracts, reliable execution loops, observable workflows, and systems that can keep improving without hiding their state.
A fast, Rust-based package manager for Node.js. Alongside package-management work, the repository is also where I experiment with spec-driven development, validation gates, and agent-assisted engineering workflows.
