Owned and architected a shared React data layer using Redux Toolkit and RTK Query, including typed endpoint slices, normalized cache keys, and tag-based invalidation to replace ad hoc fetching across 8+ features. Configured a Webpack Module Federation micro-frontend to establish shared dependency boundaries and remote versioning so multiple teams could deploy independently without duplication or version drift breaking the host shell. Built a schema-driven, multi-step approval workflow with role-based routing and field-level authorization, per-step validation, and resumable draft state adopted by 6+ business teams. Migrated feature-local global state from Redux to React Context/useReducer with scoped providers to prevent blanket re-renders, aligning the codebase with React primitives. Improved performance for high-traffic browsing via route-level code splitting, memoized selectors, list row optimizations, and per-endpoint cache lifetimes. Implemented Jest/React Testing Library tests for

Built a B2B commerce frontend for a platform selling 3D scanning, printing, and engineering solutions across 50+ partner and vendor products, covering discovery, cart, checkout, and order flows. Created an integration layer that normalized product, pricing, and inventory responses from separate services to reduce round trips and remove repeated null-handling and reconciliation logic. Implemented React/Next.js flows across 12+ product and checkout workflows by decomposing designs into reusable components with a shared prop/variant API rather than one-off pages. Developed a Socket.io support chat with optimistic UI rendering reconciled with server acknowledgments, message queueing during disconnect, and exponential-backoff reconnection with replay on resume.
