My responsibility
What I owned and contributed.
- Built a structured bra Fit Finder from authoring schema through responsive interaction, including product switching, image geometry, mobile typography, and an accessible results recap.
- Built the UGC Spotlight system with looping video carousels, drag and wheel behavior, product drawers, variant selection, comparison modes, and resilient mobile and desktop layouts.
- Engineered Gift with Purchase reconciliation with configurable products, inventory checks, paid-merchandise qualification, one-gift enforcement, and checkout locking during overlapping cart mutations.
- Implemented countdown, early-access, waitlist, and Klaviyo signup behavior with consent handling, daylight-saving safeguards, lifecycle cleanup, and merchant-configurable content.
- Maintained search-filter architecture, navigation, responsive media, accessibility, and recurring launch fixes while owning production release and QA gates.
A hard problem
Building rich interactions without letting state drift
Fit guidance, shoppable video, timed launches, and promotional cart logic all combine authorable data with fast-changing browser state. I designed each system around explicit state transitions, then hardened product switches, media loops, inventory changes, interrupted playback, overlapping cart mutations, and section reinitialization so the experience stayed correct under real interaction.
Delivery outcome
What changed, shipped, or mattered.
The work delivered multiple substantial customer-facing systems, not a single promotion feature: Fit Finder, UGC Spotlight, resilient launch and signup experiences, search and navigation improvements, and inventory-safe gifting. Frequent releases now move through explicit implementation, regression, and production QA gates; no measured business metric is attached to this project.
