ARCHITECTURAL FOUNDATION & ROLE

As Lead Backend Developer at Avisa Technologies, I architected the low-latency matchmaking engine. Leveraging Redis sorted sets and Socket.IO cluster rooms, the system pairs waiting peers within milliseconds based on geographic proximity, preferred language, and network conditions.

Key Engineering Highlights & Features

5-Second Instant Random Video Matching Engine

Low-Latency WebRTC Peer-to-Peer Video Infrastructure

Redis Sorted Sets Queue for Microsecond Pairing

Live Web Admin Dashboard for Real-Time Moderation

Automated Rate Limiting & Hardware Fingerprint Blacklisting

Geo-Distributed STUN/TURN Signaling Network

I developed the WebRTC peer-connection pipeline with global STUN/TURN traversal servers. The infrastructure achieves sub-50ms signaling speeds, adaptive resolution switching, and instantaneous peer skip/next handshakes with zero connection hanging.

67 Video Chat Admin Dashboard & Production Metrics

To safeguard users, I developed the Web Admin Moderation Dashboard. The portal provides live telemetry on concurrent video rooms, rapid abuse-flagging queues, machine-assisted reporting triages, and instant hardware/IP blacklisting.

PRODUCTION RELIABILITY & SCALE

The backend was built for extreme concurrency and throughput, operating with clustered Node.js workers and Redis memory stores to withstand massive traffic spikes during peak evening hours.
