Professional Summary

Flutter and Android engineer with 4+ years of experience building cross-platform applications, specializing in mentoring junior developers and owning features end-to-end, from initial design to production release.

At Smart Webtech, I improved rendering performance by 40% through widget optimization, lazy loading, and efficient state management.

I have mentored 3 junior developers, guiding them through Flutter fundamentals and accelerating their onboarding to production-level development. I also built native Android apps in Java (MVC) with Firebase Realtime DB and integrated Razorpay & Paytm gateways, improving transaction success by 25%.
