# Professional Journey

## Affinidi (since Jan 2025)

Affinidi is building the Internet of Trust: privacy-first infrastructure and open standards (DIDComm v2.1, OID4VCI, SD-JWT, EUDI) that connect people, businesses, and AI agents without vendor lock-in.

The platform spans verifiable credentials (Elements), trust networks and registries (Radix), end-to-end encrypted messaging, and an identity-first gateway for agentic AI (Trust Fabric). I contribute across the Affinidi Trust Network and Trust Developer Kit, including the Dart SDK for mobile.

## City-Flock (since Apr 2025)

City-Flock is a community safety app that matches people travelling in the same direction at the same time, on foot, by bike, or on public transport. Mission: make everyday journeys safer, especially for women who often avoid certain routes after dark.

Cross-platform mobile clients for Android and iOS with real-time companion matching, in-app chat, and SOS plus trusted-contacts features. Privacy is core: routes and shared information stay under the user's control. I lead mobile development and architectural decisions.
