Contributed to an e-commerce web platform with a personalized multi-step quiz funnel and recurring subscriptions. The application guides visitors through a tailored plan, converts through Stripe checkout and lets users manage their subscription — localized into 10 languages and tuned for conversion.
A funnel-driven storefront lives or dies on flow and trust: each quiz step has to feel effortless, validation must be forgiving, payments have to be reliable, and the experience must work identically across 10 locales without breaking the conversion path.
A smooth, animated quiz-to-paywall funnel with reliable Stripe checkout, self-serve subscription management and full localization — a measurable acquisition surface rather than a static marketing page.
Implemented the multi-step personalized quiz with progress UI, unit toggles, validated forms (React Hook Form + Yup) and animated step transitions (Framer Motion).
Integrated Stripe checkout, payment review and self-serve subscription management (manage and cancel) with clear states and error handling.
Wired i18next across 10 languages with locale-aware dates and units, keeping the entire funnel consistent across markets.
Connected the UI to the API with React Query, added progress charts and integrated runtime monitoring for production reliability.
