About

Software Engineer with 2+ years of experience building production-grade Android applications and SDKs using Kotlin and modern Android frameworks. At UIDAI, I work on Android systems where security, reliability, device compatibility, and real-world constraints matter. My work spans biometric integrations, camera/hardware interactions, SDK development, secure communication, and production debugging — taking problems from investigation and technical design through implementation and delivery. Previously at GimBooks, I owned features across products serving India, Saudi Arabia, and UAE, while working closely with and managing a team of developers. I’ve been involved in architectural decisions, code reviews, mentoring, and shipping transaction-critical fintech workflows. Beyond Android, I also work with Spring Boot and backend services, giving me a broader understanding of how mobile applications interact with APIs, business logic, and distributed systems. I enjoy solving problems that aren’t straightforward, understanding systems beyond the surface, and taking ownership of outcomes. 🚀 Looking for: Android SDE roles where I can own meaningful problems, work with strong engineers, and continue growing as a technical leader. ⚙️ Tech: Kotlin • Java • Jetpack Compose • Coroutines • Flow • MVVM • Clean Architecture • Retrofit • Room • Hilt • CameraX • Firebase • Spring Boot
