Software Developer — MERN Stack, Docker, AWS

I build systems end to end — auth that doesn't leak, deployment platforms that don't break, and matching engines that score what actually matters. Comfortable across full stack, backend, cloud.

Things I've built

2026

Distributed CDN Simulator

A distributed CDN architecture with a consistent-hashing load balancer, 3 edge servers, and 300 virtual nodes for request routing and node-level failure handling.

  • Cache-aside caching with TTL and single-flight deduplication to stop redundant origin requests on concurrent misses
  • Interactive monitoring dashboard — cache metrics, edge health, hash-ring visualization, cache purge

DeployForge

An end-to-end automated deployment platform inspired by Vercel — one-click static site deploys straight from a GitHub repo, zero manual steps.

  • Dockerized build server clones repos, resolves dependencies, and produces optimized builds
  • AWS S3 for storage, AWS ECS for auto-scaling container orchestration
  • Nginx reverse proxy for custom domain routing, Redis-backed job queuing, WebSocket log streaming

Resume Processing & Candidate Matching Platform

A resume processing and matching system with role-based access control across Admin, Recruiter, and Candidate roles.

  • JWT authentication and cloud-based storage on AWS S3, with role-based access control across three user types
  • Async processing pipeline using background workers, plus a weighted scoring engine matching resumes on skills, experience, and education
  • Containerized the full application with Docker and Docker Compose for reproducible environments and streamlined deploys

Socialify — Real-Time Social & Video Calling Platform

A full-stack social platform backend designed around user authentication, social connections, and real-time communication.

  • Designed a scalable Node.js + Express REST API architecture with clean separation of routes, controllers, models, and middleware for maintainability.
  • Implemented secure authentication system using JWT (HTTP-only cookies), bcrypt password hashing, and reusable protected route middleware.
  • Built core social + real-time features, including friend-request workflows, user management with MongoDB, and Stream Chat integration for live communication.

// about

A bit more context

I’m a Software Developer who enjoys building full-stack applications and solving backend and system-design problems. I like understanding how things work under the hood — from designing APIs and data flows to building interfaces that turn those systems into usable products. I’m looking for opportunities where I can build real products, contribute across the stack, solve challenging engineering problems, and keep growing as a developer.
