A Few Months in Luxembourg: EUDI, Interoperability, and Everything In Between

I spent the last few months based in Luxembourg, and it turned out to be one of the more formative stretches of my career so far.

The main reason I was there was work, specifically, deep focus time on the EUDI Wallet ecosystem. Being embedded in Europe made a real difference. Proximity to the people, the standards bodies, and the conversations happening in real time meant I could move faster and understand the context behind the spec decisions in a way that's hard to get remotely.

UNFOLD & Interop Week in Paris

The highlight was traveling to Paris for the UNFOLD event and the interoperability week that followed. These gatherings brought together wallet providers, verifiers, and identity ecosystem players from across Europe. All trying to make their implementations actually talk to each other.

We came in with one goal: prove that our stack works with everyone else's. And we did. We achieved full interoperability with France Identité, and hit 100% interoperability across all participating implementations. Seeing the pieces click together across different teams, different tech stacks, and different national contexts, that was genuinely satisfying in a way that passing your own test suite never quite is.

Beyond the Work

Luxembourg itself surprised me. It's a small country, but the density of people doing interesting things, in tech, in policy, in finance, is remarkable. I met people from all over Europe and had conversations I wouldn't have had anywhere else.

And of course, being in the heart of Europe meant weekends could look like Paris, Brussels, or somewhere entirely unexpected. It gave me a different lens for understanding how Europe thinks about identity, privacy, and digital infrastructure, not just as technical problems, but as deeply cultural ones.
