A cross-platform chat platform built on a Rust backend with end-to-end gRPC contracts, Flutter clients across mobile and desktop, and a Next.js web app. I run product for it and work in the codebase daily — roadmap and scope on one side, backend and client work on the other.
Type-safe contracts shared across every platform via gRPC, so the Rust backend and Flutter and TypeScript clients cannot drift
Offline-first architecture with local SQLite caching, so the app stays usable on unreliable connections
Real-time message streaming over WebSockets with gRPC-Web support for the browser
Sequenced roadmap through in-app purchases and a public sync API
