I don't just write code — I architect solutions to real problems.


👨‍💻 About Me

I'm a software engineer who believes in solving problems first, choosing technology second. My work focuses on real-time systems, secure authentication, and scalable backend architectures — with a strong emphasis on user experience and system design thinking.

💡 What drives me:
Understanding constraints, designing elegant solutions, and shipping products that matter.

🎯 Currently: Building production-ready applications | Seeking internship opportunities | Exploring AI-powered development workflows


🏗️ My Engineering Philosophy

const approach = {
  step1: "Understand the problem deeply",
  step2: "Map constraints & requirements", 
  step3: "Design the system architecture",
  step4: "Choose the right tech stack",
  step5: "Build, iterate, ship"
};

// Technology serves the solution, not the other way around.

🚀 Featured Projects

🎥 YT Clone — Full-Stack Video Platform

The Challenge: Building a production-grade video sharing platform with complex features like YouTube.

My Solution:

  • Architected complete video upload pipeline with Cloudinary for optimized media processing and CDN delivery
  • Implemented channel creation system with user profiles, branding, and content management
  • Built advanced search functionality with MongoDB indexing for fast video/channel discovery
  • Designed Redux Toolkit state management for predictable global state across complex features
  • Created subscription model with real-time notifications and updates
  • Developed responsive UI with seamless video playback and infinite scroll

Tech: React, Redux Toolkit, Node.js, Express, MongoDB (with indexes), Cloudinary
Impact: Full-featured video platform demonstrating end-to-end system design and scalable architecture


🔐 Passkey Authentication System

The Problem: Passwords are weak, vulnerable, and frustrating for users.

My Solution:

  • Implemented WebAuthn/FIDO2 passwordless authentication
  • Built complete registration and authentication flows with biometric support
  • Designed fallback mechanisms for cross-platform compatibility
  • Created secure credential storage with encryption best practices

Tech: Node.js, Express, WebAuthn API, MongoDB
Impact: 100% phishing-resistant authentication with zero password management


🔍 FoundIt — Lost & Found Management System

The Problem: No centralized, efficient system for reporting and claiming lost items.

My Solution:

  • Built full-stack MERN application with RESTful API design
  • Integrated location-based reporting with interactive maps
  • Implemented role-based access control and claim verification system
  • Designed intuitive UX flow reducing reporting time by 70%

Tech: React, Node.js, Express, MongoDB, Mapbox
Impact: Solving a real community problem with scalable technology
