About

Experienced Mobile Application Developer with over 7+ years of hands-on experience in building both native Android and cross-platform apps using Java, Kotlin, and React Native. I specialize in scalable mobile solutions that deliver seamless performance and engaging user experiences across platforms. In my current role at Tata Consultancy Services, I’ve played a key part in developing the NDDB BharatPashudhan app and other public-facing applications, managing end-to-end releases, integrating microservices-based backend systems, and mentoring junior developers to meet agile delivery goals. My work focuses on delivering high-quality, multilingual applications with efficient state management and secure API usage. I am passionate about clean coding principles, reusable UI components, and leveraging tools like Firebase, Redux, and i18next to improve performance, reduce crashes, and ensure broad usability. With a user-first mindset and experience in domains like education, dairy logistics, and public services, I build apps that make a meaningful difference. My goal is to continue building scalable mobile applications that integrate smart backend systems, meet business objectives, and provide intuitive user experiences in diverse sectors.
