MemeStream – AI-Moderated Social Platform

Dedicated meme-sharing platform with Google Gemini multimodal AI for automated meme detection and quality scoring at post time, real-time messaging and notifications over SignalR hubs (1:1 and group chat, read receipts), a multi-signal personalized feed (time decay, diversity interleaving, seen-post tracking) and a gamified 8-tier LaughScore ranking. JWT + BCrypt security, Docker Compose deployment. Published evaluation: 45 ms median API latency, <100 ms real-time delivery, 99.8% uptime — the research behind my first-author ECCT 2026 paper.
