Owned the hardest backend problems on the platform — real-time scale, large-scale data, and AI. • Scaled real-time infrastructure to 200K+ concurrent connections, lifting P99 reliability from 75% → 99% and shrinking the server fleet 55%. • Led backend architecture for a conversational AI product — a distributed, event-driven pipeline that grew to $500K+ ARR. • Migrated 80B+ records across MongoDB, S3 & Cassandra with zero downtime, retiring an entire database cluster. • Took an AI product 0 → 1 with the founder, and mentored engineers through architecture reviews and patterns adopted org-wide.

About

I build backend systems that stay fast and reliable when the load gets ugly. 🚀 5 years at Wayground (Quizizz) working on the hard, high-scale problems — real-time infrastructure serving 200K+ concurrent users, event-driven pipelines, and 80B-record data migrations that run with zero downtime. Lately I've been building at the frontier of AI products: leading backend architecture for conversational AI and taking a new AI product from 0 → 1 alongside the founder. Beyond the code, I care about the people who write it — I've mentored engineers, run 100+ technical interviews, and helped grow a team from 10 to 80+ without dropping the bar. Distributed systems, thoughtful architecture, and shipping things that last. Go · Node.js · TypeScript · AWS 📫 prashantsingh3553@gmail.com · 🌐 pxnt.dev
