- Hackathon Mentoring — scope-cutting and rapid prototyping for teams shipping in 24–72 hours.

## Writing

- [Your JSON-LD Is a Graph. Model Your Sanity Content Like One.](https://trzcinski.org/blog/json-ld-graph) — Set-and-forget JSON-LD leaves a search engine to guess, from a matching name, that three “Aurora” nodes are one band. A @graph says it outright — one artist, three nights — and it's the precondition you've probably already paid for, if your content model is a graph. (published 2026-06-18)
- [Scale Is a Count of Readers, Not Rows.](https://trzcinski.org/blog/schema-is-the-product) — A data model becomes a product the moment something you can't redeploy in the same commit depends on its shape. The variable isn't rows — it's how many readers are outside your blast radius. (published 2026-06-18)
- [Authors Are Not a Field.](https://trzcinski.org/blog/schema-isolation) — Isolate a concern into its own schema when it has identity, a lifecycle, or gets reused — and leave it inline when it doesn't. (published 2026-06-18)
