Problem Statement

Car owners often can't be reached when someone needs to report a parking issue, a minor accident, or an urgent situation involving their vehicle. Existing solutions require downloading apps or knowing the owner's contact.

My Role

Solo designer and developer — concept, backend, frontend, and infrastructure.

Architecture

• .NET 10 API handles QR scan events, owner lookup and notification dispatch
• Vue.js SPA provides the scanned landing page and owner management portal
• Twilio delivers instant SMS and WhatsApp notifications to the car owner
• PostgreSQL stores vehicle registrations and event history
• Redis caches QR lookups for sub-millisecond response on scan
• Docker packages the entire stack for portable deployment

Key Features

• Personalized QR codes — unique per vehicle, printed and displayed in the car window
• Instant owner notification — SMS / WhatsApp sent the moment the code is scanned
• Anonymous reporting — scanner stays anonymous; owner gets the message and a map pin
• Owner portal — manage multiple vehicles, view scan history, configure notification preferences
