At Stark Softech, I build responsive Flutter interfaces and feature modules, using Provider and Dart Streams and Futures to manage app state. I also write unit and widget tests and troubleshoot production issues.

Previously, I integrated Firebase services and REST APIs into production apps at Digiblock Network Pvt Ltd. At Hysas Technology, I developed cross-platform applications and worked with designers on responsive layouts and animations.

On Travellers Choice, I built consumer and admin app screens, integrated APIs and payment gateways, and added Firebase features and localization. I’ve also worked on Velica, a concert ticketing app with seat selection, dynamic pricing, and Stripe and PayPal payments.
