Results-driven Senior Mobile Developer with 9 years of experience.
IranI am a results-driven Senior Mobile Developer with over 9 years of experience in building high-performance Android and cross-platform mobile applications. My expertise lies in utilizing Kotlin, Java, and Flutter to create scalable, maintainable, and testable code. I specialize in Clean Architecture and state management techniques such as BLoC and Provider, which have allowed me to optimize user experiences and reduce app load times significantly.
Throughout my career, I have successfully migrated legacy Android applications to Flutter, achieving better visual consistency and UI smoothness. My role at Golrang System has been particularly rewarding, where I focused on cross-platform development and improved app performance by reducing startup times and enhancing memory management. I thrive in Agile environments, collaborating closely with designers and product managers to deliver business-driven solutions that meet user needs.
