The Dispatch

The story behind the work,
in your inbox.

Est. June 2026 Roughly weekly One click out

Each letter is a new post, sent the morning it goes live. Most of them are about what I ship: pdf-mcp, redmine-mcp-server, and my agent blueclaw. The changelog tells you what changed. The posts cover the rest: the thinking behind it, what surprised me while building it, and what the numbers said.

The rest are about the systems underneath: AWS architecture, serverless trade-offs, and what things actually cost.

Roughly weekly while I'm shipping, quiet when I'm not.
