The problem

LuxySmile needed a single website that could convince two very different buyers: school principals looking at dental wellness programs for students, and corporate HR managers evaluating team health packages. At the same time, dental staff needed an internal tool to manage patient cases - without IT infrastructure to handle large image files.

The challenge

LuxySmile Oral Care needed two things simultaneously: a premium-feeling public-facing website that would convert school administrators and corporate HR managers into B2B partners, and an internal dashboard that let dental teams manage smile design cases without routing large image files through an application server. The public site had to communicate both "luxury" and clinical credibility while keeping load times fast for a mobile-first Indian audience.

Architecture & System Design

Public marketing website targets schools and corporate wellness programs. Internal dashboard enables clinic staff to manage patient cases and treatment records. File uploads bypass application server (presigned URLs to cloud storage) for scalability. Analytics integration tracks visitor behavior and B2B conversion funnel. CSV bulk import supports onboarding existing patient data.

Full system schematic available upon request

The public product website (luxysmile.com) is a React 18 + Vite SPA with Google Analytics 4 instrumentation, React Router, and Lucide React icons. Custom CSS with brand tokens (--luxyellow, --luxgreen) provides the premium gold-and-forest-green visual identity. The internal dashboard is a separate React 18 + Vite + TypeScript SPA. File uploads use the presigned S3 URL pattern - the client requests a temporary upload URL from the backend and pushes directly to S3, keeping the app server stateless. A PapaParse-powered CSV import lets teams bulk-onboard cases from existing spreadsheets.

Results

luxysmile.com is live, serving as the primary GTM surface for LuxySmile Oral Care's school and corporate wellness programs. The site includes a full B2B inquiry flow, School Health Award positioning, and an AI kiosk (OraScan Pro) upsell. The internal dashboard handles case file management for pilot dental practices with direct-to-S3 uploads eliminating server-side file handling bottlenecks.
