Digital Craftsman &
Problem Solver

I am a dedicated software developer based in Bathinda, Punjab, India, with a passion for designing cohesive, user-centric digital experiences. My expertise spans building sleek web interfaces using React & Next.js, crafting rich cross-platform mobile environments using Flutter & Android, and managing robust, scalable server architectures with Node.js, Java, and .NET.

I hold a deep conviction that great software goes beyond simple functional execution; it should possess a classic, intuitive flow that feels completely natural and satisfying for the user.
