    I've been working with IT since 2009 and during my trajectory I realized that the most important thing between a customer and supplier relationship is trust. In these years of experience, I worked in website development, script development for servers and network administration. I also managed several projects in the technology area and that's why I can keep my work organized. At my college, I learned several programming languages, worked with some databases, but my focus is currently developing applications with Bubble.

    Good Day! I am a Flutter Developer from Pakistan with 4 years of professional experience developing cross-platform applications with Flutter. I love developing elegant user interfaces and creating best-in-class user experiences. I have used Flutter BLOC, Provider, and Riverpod as different state management solutions for my applications. I conventionally use the CLEAN architecture for Flutter using SOLID design principles and MVVM pattern. I have also worked with BLOC architecture as it provides a relatively robust separation of concern of your Business Logic from your UI. Both BLOC and CLEAN architectures are highly scalable and maintainable for writing medium to large-scale Flutter apps. I normally use Dio and Retrofit in combination with code generators like build_runner to make HTTP requests. GetIt to resolve dependencies and GoRouter (a wrapper around Navigator 2.0 ) for Navigation Other than that, I have hands-on experience working with Rest APIs, Streams, Web Sockets (MQTT, PUSHER), Notifications, Animations, Firebase (Auth, Firestore, Storage, FCM, Dynamic Linking), Google Maps SDK, Twillio Integration, and Integrating other third-party SDKs. I can be a Freelance contractor in developing your next beautiful Flutter application or I can be a powerful addition to your team if you are looking for a collaborator. Want to talk about your next Big Idea? Let's meet and discuss more.
