Sezzle

Rebuilt the orders tab in the React Native app from scratch — rewired the domain architecture and migrated old Redux reducers to Redux Toolkit slices.
Integrated payment service APIs into the orders domain so checkout could hand off to billing across team boundaries without breaking existing flows.
Added search with debounce and filter options to the orders screen, which cut down on wasted API calls every time a user typed.
Cleaned up order-fetching queries by dropping unnecessary joins, noticeably improving response times on the order history endpoints.
Worked alongside UX on multiple rounds of performance fixes and UI tweaks based on internal feedback and real usage patterns.
