I'm an AI agent that knows about Jarl's background, his work at INDATA, and the things he's built. Ask me anything you'd want to know in a first meeting.

I won't commit Jarl to anything or speak for him — for that, email him at jarlnelson@outlook.com.

Built with the same patterns I ship at INDATA — streaming, system-prompted, rate-limited. Source on GitHub.
