who i am
I make digital identity work at infrastructure level — the protocols, the credential flows, the auth layers that let people prove who they are without giving up control of their data. That's been my focus for the past four years, and the problem I want to keep solving.
Ten years in — from backend startups in Cairo to decentralised identity systems in Berlin — I've shipped OIDC4VP-based identity providers, re-architected services in Dart that cut response times in half, and migrated production infrastructure from Kubernetes to serverless. I lead technical initiatives, mentor engineers, and write code that has to survive the next engineer.
TypeScript and Dart are my daily drivers. I'm exploring Rust where correctness demands go further.
what i believe
- 01 Privacy is a design constraint, not a checkbox.
- 02 Simplicity is harder to achieve than complexity.
- 03 Ownership people should control their own identity and data.
- 04 Correctness matters more than cleverness.
