Loopedin
A next-generation social platform that fuses short-form video with live, local event discovery — engineered to stay real-time at the scale of millions.
01//the problem
Social feeds and event discovery usually live in two separate apps, and neither is built to carry millions of people sharing video and messaging at the same instant. Loopedin had to be both — a short-form video feed and a live local-events layer — under one roof, without the latency or cloud bill exploding as the audience grew.
02//the approach
I architected Loopedin as a set of independent Node.js microservices on AWS so each concern — video, messaging, events, scoring — could scale on its own. A serverless pipeline on AWS MediaConvert handles video transcoding, Socket.io backed by Redis powers real-time messaging and presence, and a gamified LoopScore engine keeps engagement compounding.
03//what I built
Serverless video pipeline
Upload-to-playback transcoding on AWS MediaConvert, so video scales without dedicated media servers.
Real-time messaging
Socket.io + Redis deliver low-latency chat, presence and notifications across millions of sessions.
Live event discovery
A location-aware events layer surfaces what's happening nearby, blended straight into the feed.
LoopScore engine
A gamified scoring system that rewards activity and keeps retention high.
// the impact
Loopedin now reaches 2.4M+ users and has carried 96.3M+ messages and 4.8M+ shared videos — all on infrastructure that holds 99.9% uptime under real load.
“The hard part was never a single feature — it was keeping everything real-time while the numbers kept climbing. That's an architecture problem, and it's the part I love.”
