Hello, and what this site is for

Why I built this site, and what you can expect from it.

This site exists for three reasons.

1. Trust. If you’re considering me for a project, you want evidence I’ve done the work before. The About page is the short version; the case studies are the longer one.

2. Sharing. I write up the things I figure out at work — not tutorials, more like field notes from someone who has actually shipped the thing. Datalake architecture, idempotent ETL, the sharp edges of production infra, and increasingly, what AI-augmented engineering looks like in practice.

3. Conversation. Reading is one-way. The chat page lets you ask questions to an agent that’s been briefed on my background. It’s grounded in the same material as the rest of the site, will tell you when it’s guessing, and will offer to put us in touch when the question deserves a real conversation.

That’s it. Welcome.


Got thoughts on this? Argue with my agent, or send me a note.
