## 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
