Sober Social & Dating Platform

01 / The Challenge & Problem

Sober communities lack dedicated spaces to connect without the pressure of alcohol-centric environments. The challenge was building a highly interactive, real-time social networking and dating app that guarantees extreme privacy, safety, and instant message delivery.

02 / Discovery & Research

Our research revealed that sober app users prioritize profile verification and strict community safety rules. Technically, we discovered that standard HTTP polling caused massive server loads and rapid battery drain, requiring a lightweight, persistent connection paradigm.

03 / Construction & Development

We engineered the client in React Native and Expo, utilizing SQLite for offline message storage. On the server, we developed a custom NestJS WebSocket adapter, integrating Redis to broker active user sessions. To comply with HIPAA-like security needs, all message payloads are encrypted end-to-end.
