Key Strengths

  • End-to-end frontend product leadership (React Native/Expo) for real users handling sensitive financial data
  • Scalable frontend architecture design (feature-based structure, shared UI primitives, strict TypeScript typing)
  • Strong testing discipline for UI quality at scale (Jest + React Native Testing Library; accessibility and edge-case coverage)
  • Real-time UI/state synchronization strategy (server as source of truth; resilient to out-of-order/partial updates; queued actions; optimistic updates with rollback)
  • Codebase modernization and reusability improvements (component library, modular state via context + hooks)
  • Performance optimization in existing React apps (audit, lazy loading, memoization, reducing re-renders)
  • Shipping major features under tight timelines with controlled rollout (MVP milestones, feature flags, staged release, analytics-driven iteration)
  • Cross-functional collaboration with product/design from early wireframes through iterative feedback loops
