About

Professional summary

I am a mobile app developer with more than 3.5 years of experience building and releasing production Android, Flutter, and React Native applications. I specialize in Kotlin, Java, Dart, and JavaScript, with a focus on reliable, high-performing mobile experiences.

I have developed fintech applications for a housing finance company, including customer loan tracking, KYC document upload, agent workflows, in-app chat, notifications, dashboards, and location-based features. My work has supported both customer-facing and field-agent mobile products.

I am experienced with native Android development using Android SDK, Jetpack Compose, MVVM, Coroutines, Flow, Room, Retrofit, Hilt, and Firebase. I also build cross-platform applications with Flutter and BLoC, and have contributed React Native screens and bug fixes.

I work closely with backend and QA teams to integrate REST APIs, resolve production issues, improve app performance, and maintain release quality. I have implemented caching, lazy loading, offline behavior, image optimization, and API-call improvements to reduce screen load times and UI lag.

I am comfortable managing the full app delivery lifecycle, including automated testing, CI/CD pipelines, Google Play publishing, App Store submissions, versioning, policy compliance, and production monitoring. I also enjoy sharing mobile development knowledge through seminars at colleges and industry meetups across Delhi NCR.
