Gathr

Production social app built on the decentralized Nostr protocol. I architected the full Flutter client, event-driven state management, and Node.js services — shipped to real users on iOS and Android.

01 / Challenge

Gathr needed a production social app bridging decentralized Nostr protocol with polished mobile UX — something no team had shipped at scale.

02 / What I Built

Built the full Flutter client, designed event-driven state management across Nostr + Node.js + Firebase, and shipped to iOS and Android.

03 / Results

  • →Shipped production app to real users on iOS and Android
  • →Designed cross-platform architecture: Flutter + Nostr + Node.js
  • →Real-time event-driven state management across decentralized protocol
  • →Cloud infrastructure and backend services managed end-to-end
