🔹 Android Engineer with 4+ years of experience building and optimizing consumer apps that serve over 100 million users. 🔹 At Flipkart, I led performance, platform, and payment initiatives—building Flipkart UPI from scratch, spearheading a low‑code development platform that slashed feature rollout time by 40%, and improving core metrics (cold app start, ANRs, crash rates) critical for user retention. 🔹 My strengths include Kotlin, Jetpack, Android architecture patterns (MVVM/MVI), React Native, WebView, and crafting scalable mobile platforms. I’m passionate about product‑driven development, shipping impactful features, and optimizing apps for speed and quality. 🔹 Previously at CREX and now at Freshworks, I delivered full‑stack mobile solutions under tight deadlines while maintaining high code standards and performance. 💼 Currently exploring senior Android roles in global tech hubs (London, EU, US) or remote‑first teams. Core Skills: Android (Kotlin, Java), Jetpack Compose, React Native, Clean Architecture, Dagger/Hilt, Performance Optimization, Firebase, Retrofit, Payments/UPI 📬 Open to connections, referrals, and global Android product opportunities!
