I build identity infrastructure that doesn't watch you.
I’m CTO at Yivi, the privacy-first identity wallet, and at Caesar Groep. Two problems occupy me: making digital identity work at national scale without building a surveillance layer, and rebuilding how engineering teams operate now that agents write most of the first draft.
Before this I spent a decade as a cloud architect, mostly deep in Azure — search scoring, serverless integration, governance frameworks. That writing is still in the archive and still gets read, which is either a compliment or a comment on the documentation.
Digital identity
Wallets, verifiable credentials, the European framework, selective disclosure, trust registries. Written from operating a live scheme rather than from the spec.
Agentic coding
Agent workflows, evals for your own pipeline, review at volume, and what all of it does to team structure and hiring.
I talk at conferences and internal engineering days about identity architecture and about running teams that ship with agents. Slides and recordings are linked from each talk.
