Oakland, California

Hi, I’m Jason.

My work spans developer platforms, infrastructure, and AI-supported products, usually alongside teams solving difficult systems problems.

This is a small collection of things I’ve built: side projects and experiments, mostly for fun and learning. Nothing for sale here, just work I enjoyed making.

Building now, where AI meets useful software.

LLM-Now is the newest release, followed by three active projects across AI, recall, and personal knowledge.

Newest open-source release

LLM-Now

One command for the LLM providers you already use.

LLM-Now discovers local, CLI, and cloud providers, saves reusable shortcuts, and keeps model output clean for scripts and pipes.

brew install swartzrock/tap/llm-now

From diff to commit.

Use a local, CLI, or cloud model to draft commit messages without leaving Lazygit.
