I led the architecture of a mobile banking Kotlin-based app project, ensuring it was scalable, maintainable, and aligned with modern best practices. I implemented a domain-driven design (DDD) approach using a multi-module structure, separating concerns into presentation, domain, and data layers. This architecture allowed for better testability, modular development, and clear business logic and UI boundaries.

I also integrated CI/CD pipelines, enabling automated builds, testing, and deployment processes. These efforts improved the overall development workflow, reduced manual errors, and allowed faster delivery of new features. My role also involved collaborating closely with cross-functional teams, setting up coding standards, and conducting code reviews to ensure consistency and high code quality across the project.

I spearheaded the development of the BM Online UAE application from scratch using Kotlin, implementing a Domain-driven Design architecture to ensure scalability and maintainability. The project featured robust unit testing with over 85% coverage and integrated SonarQube for continuous code quality monitoring within CI/CD pipelines. By leveraging Jetpack Components and Clean Architecture, I delivered a production-ready financial platform with zero critical defects, achieving a 4.8+ Play Store rating. This greenfield project established a strong foundation for future fintech innovation while meeting strict compliance standards.

I contributed as a key developer on a healthcare application, designing and implementing critical features while ensuring robust Bluetooth integration for seamless medical device connectivity. Leveraging Kotlin and modern Android architecture, I enhanced the app's reliability by introducing comprehensive unit testing and improving code quality. My work helped deliver a stable, user-friendly platform that meets strict healthcare compliance standards while maintaining high performance for both patients and providers.

Designed and implemented secure financial features while enhancing the app's stability through comprehensive unit testing. Using Kotlin and modern Android architecture patterns, I contributed to critical functionality like transaction processing and authentication while maintaining strict compliance standards. My focus on test-driven development and code quality helped deliver a reliable banking platform with robust performance and security for end-users.

I played a key role in migrating the native Kotlin codebase to React Native while implementing critical features like secure video call functionality for customer support. I ensured the hybrid solution maintained the app's banking-grade security standards and smooth performance by optimizing the bridge between native modules and React Native. Additionally, I strengthened the project's reliability by introducing comprehensive unit testing and modern CI/CD practices throughout the transition.
