From curious computer science student to co-founding a startup
Started my journey at NED University, where I discovered my passion for mobile development. While others were building web apps, I was fascinated by the idea of creating something people could carry in their pockets.
Joined Reactree as a Flutter Developer. This is where I learned that clean code isn't just about making it work—it's about making it maintainable, scalable, and beautiful. Spent 2.5 years mastering the craft.
Co-founded KalPal, a nutrition tracking app. From idea to beta launch, I architected the entire technical stack. This taught me that being a developer isn't just about writing code—it's about solving real problems for real people.
I don't just build apps, I solve problems that matter to people.
Clean, maintainable code isn't optional—it's essential.
From AWS to German, I'm always expanding my horizons.
I'm a passionate Flutter developer based in Karachi, Pakistan, with over 4 years of experience in cross-platform mobile development. I specialize in building scalable, efficient applications with clean architecture principles.
My expertise spans across Firebase integration, payment systems (Stripe, Tap Payments), subscription management (RevenueCat), and state management with GetX. I've successfully deployed multiple apps to both App Store and Play Store.
Beyond coding, I enjoy mentoring junior developers, exploring new technologies like AWS, and learning German. When I'm not coding, you'll find me traveling, watching anime, staying fit, or meeting new people.

"As the co-founder and lead Flutter developer, I built the entire frontend for KalPal — a modern nutrition tracking app that leverages AI to help users improve their eating habits without the need for manual food logging or complex databases."
I implemented a clean, scalable Flutter architecture using GetX and the repository pattern, focusing on responsive UI, smooth user interactions, and seamless integration with backend AI services. The app uses Firebase for user authentication and state sync, and RevenueCat to handle cross-platform in-app subscriptions. KalPal is currently in beta testing and has received strong early feedback for its ease of use and intuitive design.
