Rockstar🎓
Top SchoolRobbie Hanson is a seasoned iOS engineer and technical founder with 18 years of experience building secure, production-grade mobile and backend systems. He has shipped privacy-focused apps and infrastructure—from co-founding E2EE cloud sync services and writing serverless TypeScript backends to contributing critical pieces of popular open-source Cocoa libraries like CocoaHTTPServer and CocoaLumberjack. At ACINQ he worked on Phoenix Wallet, implementing UI, background sync/backup, and Kotlin Multiplatform components for a self-custodial Lightning wallet, and earlier roles span secure messaging, VoIP, and realtime social features. Robbie blends low-level networking and protocol expertise (sockets, WebDAV, XMPP, NAT traversal) with practical product instincts, and has a track record of delivering both client-facing UX and robust server-side tooling. He’s equally comfortable refactoring core libraries as he is designing end-to-end encrypted systems and blockchain integrations, making him a pragmatic engineer who favors reliability and security.
