Building high-performance Android & multiplatform
experiences at scale.
I'm an Android Engineer with 9+ years of experience building robust, user-centric apps with Kotlin, Jetpack Compose and MVVM Clean Architecture. I've led Android development for high-impact apps like ET Markets, The Economic Times and Domino's, achieving over 99.5% crash-free sessions. I also architected reusable modules that significantly reduced development effort and have since been adopted by other apps across the organization.
More recently, I've been working with Kotlin Multiplatform (KMP) and Compose Multiplatform (CMP) to share business logic and UI across Android and iOS, which speeds up delivery and keeps the experience consistent on both platforms.
Day to day, I design and ship scalable solutions that millions of users rely on, and I own core modules for subscriptions, AI features and platform infrastructure. I use agentic AI tools like Claude Code, Cursor and Gemini to move faster without compromising on quality. I work closely with Product, Design, Business and Backend teams to turn ideas into reliable, well-crafted features.
