Flutter Developer

Savvy Solutions MMC • Full-time

Apr 2025 - Dec 2025 • 8 mos

At Savvy Solutions MMC, I worked as a Chief Technology Officer (CTO) and Flutter Developer, where I led the development of cross-platform mobile applications for Android and iOS using Flutter. I was responsible for managing the technical team, designing scalable application architectures, and overseeing the entire product development lifecycle from planning to deployment. I integrated REST APIs, payment gateways, and cloud services such as Firebase while ensuring high performance and clean code standards. During my time there, I successfully delivered multiple mobile applications, improved development efficiency through Flutter’s single codebase approach, and strengthened the overall stability and performance of the apps. My expertise includes Flutter, Dart, Firebase, REST APIs, GetX, SQL databases, and integration of services like Google Maps, Stripe, PayPal, and push notifications.
