Parveen Kumar

Hi, I’m Parveen Kumar, a Full Stack Mobile Developer with over 8 years of experience crafting smart, efficient, and scalable applications.

My journey started with Android native development, where I learned the foundations of solid architecture, performance tuning, and user-first design. Over the years, I expanded into Flutter to deliver cross-platform apps that provide the same native-quality experience on both iOS and Android.

But my curiosity didn’t stop there — I stepped into the backend world with Node.js, Express, and MongoDB, building robust APIs, authentication systems, and real-time features using Socket.io and Firebase.

Today, I bring end-to-end expertise to every project — from concept and design to deployment and maintenance.
