Message

At Sonrisa, I’m building components for the EU Digital Identity Wallet under eIDAS 2.0. I implemented issuance flows for six credential types across SD-JWT VC and mDoc/mDL, including mDoc issuance with HSM-backed document signing.

I’ve also implemented X.509 certificate-chain validation and worked on inter-service flows across Wallet Provider, PID Provider, and PubEAA Provider roles. At Prisma Solutions, I owned end-to-end feature delivery for multi-tenant Java/Spring Boot products and built integration and end-to-end test suites.
