My contribution

I created and developed ToOn: a Flutter app, React panel and Go API. My work covers real-time communication, private media, notifications and Render hosting.

How the system is organized

A Flutter app and React panel use a Go API. WebSocket, private media and notifications have separate components.

Technical structure

Technology by module.

App, API and web share the communication experience, with real-time transport separate from storage.

Authentication, contact, conversation and message modules use HTTP, WebSocket, database and storage adapters.

System

Product web surface.

React navigation and interface composition, using API contracts.

How the parts connect

Web and app communicate with the API. WebSocket handles real-time events. Persistent history and media storage have separate roles.

Data and integrations

PostgreSQL stores central data; Redis supports operations. Private media uses S3-compatible storage in Cloudflare R2, as documented in operations. SQLCipher provides encrypted local app storage.
