01About

Engineering for production, not demos.

I build cross-platform applications with Flutter and Dart, with 2+ years of professional experience across FinTech, EdTech, News, POS and Commerce. My work centres on Clean Architecture and disciplined state management — BLoC, GetX, GetIt and GoRouter — keeping presentation, domain and data concerns properly separated so codebases stay modular, testable and maintainable.

Day to day that means secure authentication and API workflows with Dio, JWT/OAuth and biometric auth; offline-first persistence with Hive and caching that holds up in low-connectivity environments; payment gateway integrations; and real-time notifications through Firebase Cloud Messaging. I have also modernised legacy mobile apps through technology migration, including taking ANI News from React Native to Flutter.
