Experience
Software Developer · Driffle
- Migrated the storefront from CSR to SSR, cutting FCP by 40% (~2s) and LCP to 2.3s, lifting the Lighthouse score by 30% and organic traffic with it.
- Integrated MoEngage end-to-end for web push and event tracking — a 10% retention increase and 5% conversion boost.
- Tuned React Native performance with Hot Updater, Hermes and ProGuard/R8, enabling OTA fixes without a store release, plus a smaller Android build via architecture splits and faster cold starts. Migrated FlatList to FlashList.

- Replaced the WebView checkout with native VISA and UPI payments, and added Astropay for localized international payments on web.

- Shipped a complaint management platform with real-time Firebase Cloud Messaging, speeding up retailer issue resolution.
