Architect tactile, gesture-driven interactions such as mystery pack tears, loot-box carousel reveals, card flips, and real-time drop tickers using TypeScript, React Native Reanimated, Gesture Handler, and Skia.
Identify and eliminate thread bottlenecks, dropped frames, sluggish view hierarchies, and memory leaks across iOS and Android devices.
Build resilient mobile query pipelines with GraphQL and TanStack Query, including optimistic cache updates, pagination, network dropout handling, and reconnection reconciliation during live unboxings.
