The Challenge
Migrating a large legacy Java codebase to Kotlin without breaking an internationally distributed app, while adding real-time chat infrastructure and improving monetization — all under tight release schedules.
The Solution
Executed an incremental Java-to-Kotlin migration using Kotlin's Java interoperability. Pusher was integrated as the real-time chat backbone with a custom message queue for offline tolerance. AdMob and IAP monetization was A/B tested across user segments.
Outcome
99% crash-free sessions globally, a 15% engagement uplift from real-time chat, and a 10% sales increase through optimized IAP and AdMob revenue strategies.
