About

I am a Lead Android Engineer with over 6 years of experience building secure, scalable, and high-performance native applications—with a deep 3.5+ year focus on Fintech and banking ecosystems. Throughout my career, I’ve specialized in taking complex mobile applications from concept to launch. I blend strong technical implementation (Kotlin, Jetpack Compose, Clean Architecture) with rigorous security standards (RBI/PCI-DSS compliance, Keystore encryption) to protect user data without compromising on interface responsiveness. Beyond writing clean, reactive code, I thrive on guiding engineering teams, optimizing development pipelines, and reducing technical debt to help organizations ship better features, faster. Key Milestones: - Architected a greenfield Fortune 100 Credit Card Management app from scratch. - Elevated app stability from an 80% crash-free rate to 98% within 6 months. - Recognized with multiple awards for Engineering Productivity, Architecture & Delivery Excellence, and UI Innovation
