+description: |
+  - Led the architecture and hands-on development of Beam, a cross-platform end-to-end encrypted (E2EE) mobile messaging application built in React Native, directing a 6-engineer cross-functional team across mobile, infrastructure, and product.
+  - Architected and managed a self-hosted Matrix homeserver, customizing the decentralized Matrix protocol to deliver end-to-end encrypted (E2EE), censorship-resistant messaging with self-custodied message history.
+  - Engineered a passkey-based authentication layer as a drop-in replacement for the Matrix authorization server, swapping centralized email/phone login for WebAuthn passkey wallets and Sonr Decentralized Identifiers (DIDs) to enable passwordless, self-sovereign onboarding and cryptographic key exchange.
+  - Abstracted decentralized routing and cryptographic key management behind a Web2-grade chat UX, guiding frontend and product teams to deliver a frictionless messaging experience over fully decentralized identity and transport infrastructure.
