Saurabh Kanswal

I’m a senior mobile engineer with 5 years of experience building mobile apps used by millions of users. I focus on performance, stability, and shipping user-centered product improvements end to end.

At Wayground (formerly Quizizz), I’ve driven cross-platform decisions by leading POCs across Flutter, React Native, Ionic, and Capacitor—then recommending and driving adoption of Flutter. I also own product strategy for new mobile experiences, from user research and interviews to UX and roadmap definition.

Deep in the code, I’ve improved gameplay performance by reducing CPU utilization by 18%, input lag by 19%, and re-renders by 23%, plus cutting mobile startup time (P95) from 13 seconds to under 5. I’ve implemented OTA updates with CodePush and later built an in-house solution with BSPatch, reducing update bundle size by 90%, and introduced MVVM architecture to reduce bugs and improve codebase abstraction.

I’ve also handled high-impact migrations, including moving React Native experiences to WebView with full feature parity via a WebView bridge and delivering the migration with zero P0/P1 bugs. I’m comfortable spanning mobile and frontend delivery—strengthening stability while raising development efficiency.
