I've owned the frontend for a real-time, map-based facility-search platform at Publicis Sapient, supporting a Fortune 500 logistics and healthcare client. I rebuilt it end-to-end in modern JavaScript, reducing page load time by 38% across 200+ geolocated facilities.

I build responsive single-page experiences with real-time map interactions, tiered keyword and proximity search, browser geolocation, Haversine distance calculations, and Supercluster marker clustering. My work reduced average search-to-result time to around 400ms and contributed to a reported ~4% improvement in qualified leads.

I work closely with design and QA to turn Figma designs into pixel-perfect, WCAG-aligned interfaces, while improving reliability through error handling, code-splitting, lazy loading, and centralized state management.

I've also built OrbitShop, a React e-commerce platform with Firebase authentication and checkout flows, and OpenAero, an interactive weather map with live conditions, forecasts, AQI, TanStack Query caching, and Zod validation.
