- Successfully migrated Shopify Mobile and Shopify POS to React Native's New Architecture with no disruption to feature development.
- Migration strategy focused on minimal code changes, dual architecture compatibility, and maintaining performance/stability.
- Key technical challenges included state batching issues, blank screens from TurboModule errors, and view flattening side effects.
- Rollout was gradual, starting with Android due to better Play Store control, followed by iOS with careful monitoring.
- Performance improvements included 10% faster Android launch times and smoother screen rendering with measure before paint.
- Post-migration, focus shifts to optimization, including TurboModule migration and synchronous layout adoption.
- Collaboration with Meta and Software Mansion helped resolve performance issues, benefiting the broader React Native community.
