About Me

The Developer

I’m a Full Stack MERN Developer passionate about building scalable, production-grade web applications with a strong focus on backend architecture, performance optimization, realtime systems, and exceptional user experiences.

The Experience

I’ve worked on real-world client projects and managed complete application lifecycles — from architecture and backend system design to deployment, hosting, optimization, and production maintenance. I’ve developed and deployed live production platforms, including The House of Rani, along with custom client portfolio websites featuring advanced GSAP and Framer Motion animations.

Backend & Architecture

I focus heavily on Node.js, Express.js, MongoDB, Redis, Socket.IO, Docker, AWS services, scalable API architecture, authentication security, caching strategies, and production system optimization.

Frontend & UI/UX

I work extensively with React, Next.js, TailwindCSS, GSAP, and Framer Motion to create responsive and visually engaging interfaces.

I’m especially interested in:
Scalable Backend Engineering
System Design & Architecture
Realtime Systems
Authentication & Security
Caching & Performance
Distributed Systems
Production-grade Infrastructure

Beyond The Code

When I'm not writing code or debugging servers, here is what I love doing.

My Pack

Spending quality time with my dog and loved ones is my ultimate reset button.

Foodie

Always hunting for the best local spots. I'll travel 50 miles for authentic street food.

Wanderlust

Exploring new cultures and hidden gems. Mountains over beaches any day.

Night Drives

Late night drives with lo-fi beats is my ultimate therapy session.

Biking

There's nothing quite like the freedom of an open road and a roaring engine.

Cricket

Treating every weekend gully cricket match like it's the World Cup final.

"I believe great software is not just about functionality — it’s about building reliable, scalable systems that can handle real users, real traffic, and deliver smooth, memorable user experiences."
