Sep 2018 - Present • 7 yrs 11 mos

Over the past 7 years, I have worked as an independent mobile app developer, specializing in native Android development (Java, Kotlin) and cross-platform development using Flutter (Dart). I have delivered 30+ mobile applications for clients across e-commerce, fintech, healthcare, education, and social networking industries, helping startups and businesses turn their ideas into fully functional, scalable products. My work covers the complete app development lifecycle — from requirement analysis and UI/UX implementation to backend integration, testing, and publishing on the Play Store and App Store. I follow clean architecture principles such as MVVM, MVI, and Bloc/Provider/GetX for Flutter projects, ensuring code that is maintainable, testable, and easy to scale. I have strong experience integrating REST APIs, GraphQL, Firebase (Authentication, Firestore, Cloud Messaging, Crashlytics), payment gateways, and third-party SDKs. I also specialize in improving existing apps — fixing bugs, optimizing performance, upgrading outdated codebases, and migrating native apps to Flutter for broader platform reach. Throughout my career, I have built long-term relationships with clients by prioritizing clear communication, transparent timelines, and reliable delivery. Whether the project requires a native Android app or a single Flutter codebase for both platforms, I bring the technical expertise and attention to detail needed to deliver high-quality results that meet business goals and user expectations.
