# About

I'm a founding engineer at [Inth](https://inth.com) (YC P26) and co-author of [c15t](https://c15t.com), the open-source consent layer.

Consent tooling is usually the worst code on a page: a third-party script bolted on the week before launch, dragging down performance and ignoring your design system. c15t exists so it doesn't have to be — consent you ship in your own bundle and components, reviewed like the rest of your code.

At Inth I'm building the rest of the compliance stack on the same idea: [DSAR](https://dsar-sdk.com) for programmatic data-rights requests, [Cookiebench](https://cookiebench.com) for measuring what consent tooling actually costs, and [Leadtype](https://leadtype.dev) for docs that agents can read. Compliance belongs in code.
