I’m a Full Stack Developer with 4+ years of hands-on experience building and shipping production web applications. I enjoy owning features end-to-end—from database schema design through frontend delivery—and I’ve done that in both internship and freelance client environments.

In my Full Stack Development Intern role at Nest Software (Amritsar), I designed and developed end-to-end features using React, Laravel, and MySQL, from requirement gathering through deployment in a production project management system. I built and optimized UI pages to improve usability and performance across key workflows, and I debugged production issues to reduce system errors and improve stability. Working in an Agile team, I contributed to feature planning, code reviews, and system design decisions.

As a Freelance Wordpress Developer (May 2021 – Present), I build and maintain e-commerce stores for 3+ paying clients—handling product listings, inventory management, payment gateway integration, and shipping configuration. For Raag (Clothing Brand), I delivered a WooCommerce store and improved page load speed by ~35% using image compression, lazy loading, and caching, along with SEO metadata configuration.

On the projects side, I’ve built a cosine similarity-based Movie Recommendation Engine using Next.js 14, React 18, TypeScript, and MongoDB (with a similarity threshold >0.4). I also developed a real-time chat application with JWT authentication and live message delivery using Socket.io and Redis, deployed via Vercel, and created SmartSched to resolve timetable conflicts with role-based access using JWT and Passport.js.
