Nathi Krithin

I’m a 3rd-year Computer Science student building production-grade full-stack systems. I’ve been solo-architecting CodeDuelz, a competitive coding platform where I deployed and defended against real-world DDoS attacks while maintaining 99.9% uptime, reaching 4.8k+ unique visitors, 300+ sign-ups in the first month, and a 1,400+ student community from 20+ colleges.

In my S Combinator Full Stack Engineer Intern role, I architected a N-Game Factory Engine using a matrix-based Component Registry to decouple UI from game logic and ship 60+ cognitive assessment mini-games. I also restructured a Next.js + TypeScript monorepo for scalable separation of concerns and built a real-time telemetry & behavioral analytics pipeline measuring latency, accuracy, and phase interactions for K-12 neurodevelopmental assessments.

I focus on practical AI pipelines (Google Gemini), reliable backend systems (Node.js, PostgreSQL, Redis), and security-hardened infrastructure. My work has included live security hardening, real-time JWT WebSocket auth, and performance-optimized automation, and I’ve been recognized as a Top 42 finalist at CrftHq Demo Day with a hosted high-scale tournament on CodeDuelz.
