I’m a full-stack developer specializing in the MERN stack, focused on building production-ready applications—from role-based authentication systems to real-time features using WebSockets. I enjoy architecting scalable REST APIs and responsive React interfaces with clean, maintainable code.

In my projects, I’ve built secure, user-focused experiences and paid close attention to performance and data behavior. For example, I engineered MongoDB native connection pooling for serverless environments and created a quick-access demo panel.

My work includes ShifaCare, where I implemented secure multi-role access (Admin/Doctor/Patient) using BetterAuth with structurally locked administrative accounts. I also reduced message latency in real-time chat by combining Pusher WebSockets with TanStack Query for real-time updates without page refresh.

I’ve also developed e-commerce and food applications with practical features like Stripe payments, Firebase authentication, an Admin dashboard, dynamic product catalogs, and mobile-responsive UI. I’m currently pursuing a Bachelor of Honours and hold a Programming Hero certificate in Complete Web Development (MERN Stack).
