# 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.

Inth is an AI-native compliance team. I build the open-source infrastructure that lets fast-growing companies manage consent, data rights, policy evidence, and vendor oversight in code, so teams can ship without waiting on legacy compliance workflows.

My work there spans the compliance stack: the c15t cookie banner, programmatic DSAR flows, performance benchmarking with Cookiebench, and agent-ready docs with Leadtype.
