About Rajan Gupta

Senior Android Engineer with 7+ years of experience designing and scaling production-grade Android applications. Strong expertise in Clean Architecture, MVVM/MVI, and modular system design, with a deep focus on performance optimization, ANR reduction, crash diagnostics, and long-term app stability.I lead end-to-end Android development, driving architecture decisions, code quality, and release stability. Experienced in building resilient mobile systems with efficient background processing, optimized memory management, and scalable offline-first data layers. I have also developed reusable SDKs and libraries to support modular development and third-party integrations.My core stack includes Kotlin, Jetpack, Jetpack Compose, Coroutines, Flow, Room, Retrofit, and CI/CD. I focus on maintainable architectures that scale, perform reliably under load, and reduce technical debt. I also bring cross-platform exposure through Flutter.Engineering Impact Highlights• Reduced ANR rates by up to 40–60% through threading and lifecycle optimization• Lowered production crash rates by 30%+ via stability engineering and memory leak fixes• Improved app startup performance by 20–35% through cold-start optimization• Designed modular architectures that improved scalability and reduced development time• Built reusable SDKs and internal libraries for faster integrations• Enhanced offline capability and reduced API load through data-layer optimization• Improved release stability across multiple production app versions• Mentored developers and elevated code quality standards
