Social Network Platform Application System

Built from scratch before the generative-AI coding-assistant era, this was my hands-on implementation of a Twitter-inspired social platform. I designed and implemented the full stack myself, from the React interface and API layer to data storage, caching, graph relationships, and real-time communication.

The system includes authentication, posts and interactions, friend relationships, real-time messaging, notifications, search, recommendation, caching, and graph-based social analysis.
