Flutter with Flair • Fulltime

Jul 2021 - Present • 4 yrs 10 mos

I am a Senior Mobile App Developer with around 5+ years of experience, currently working at Tentwenty, a Dubai-based digital agency. At Tentwenty, I have been leading and contributing to scalable mobile applications, mainly using Kotlin and modern Android architectures like MVVM and Clean Architecture. I’ve worked on multi-module projects with complex features such as payments, user management, dashboards, and API integrations. I regularly collaborate with cross-functional teams including backend, design, and product to deliver high-quality applications. Recently, I have also been focusing on Flutter for cross-platform development, applying the same architectural principles to build maintainable and scalable apps. I am passionate about writing clean, efficient code and optimizing performance, and I’m now looking for opportunities where I can contribute to large-scale applications and grow further in architecture and leadership.
