Riddle

Riddle is a social network in development, built around real-time exchanges. The project is a testing ground for everything real-time, on the server and in the mobile app.

Design and development, solo for now. I define the product, the API and the mobile app.

The AdonisJS API exposes a REST layer for persistent data and a WebSocket layer for live events: messages, presence, notifications. Data is stored in PostgreSQL.

The mobile app is in React Native. It keeps a WebSocket connection open and reconciles incoming events with local state to stay consistent even after a network drop.

Real time raises questions that REST hides well: event ordering, reconnection, state shared across several devices. Designing the event model before the interface saved me many rewrites.
