About Me

I'm a backend engineer and CS student who loves building systems that are fast, resilient, and elegant under the hood. My work spans real-time platforms, distributed architectures, and AI inference pipelines.

At DefendAir Technologies, I built scalable backend integrations for AI inference results, deployed containerized services in production, and designed data pipelines for drone-captured data.

I care deeply about distributed systems, event-driven architecture, and writing code that scales gracefully. When I'm not building, I'm exploring new patterns in systems design and AI backends.

What I've Built

Clash of DSA

↗ Live GitHub

A real-time 1v1 competitive coding platform where developers battle head-to-head solving DSA problems live. Built with a full microservices architecture, Redis-based matchmaking, and sandboxed code execution.

Microservices monorepo with Turborepo — 3 backend services + shared packages
Real-time multiplayer system using 20+ Socket.IO events for matchmaking & match state
Redis-based Elo matchmaking engine with adaptive rating search
Secure sandboxed code execution using Node.js VM with per-test-case isolation
Distributed job processing via BullMQ for code evaluation pipelines
Multi-layer DDoS protection: Nginx rate limiting + Express throttling + edge middleware
Deployed on AWS EC2 with S3 + CloudFront CDN for global low-latency delivery
