Private chauffeur booking platform.
QUELVO is a full private chauffeur service and booking platform developed by JCDM Technologies. Passengers book rides directly — airport transfers, hourly, events and city-to-city. Every ride includes Music Ride, the shared in-car music experience.
Custom-built HTML/JS multi-form booking with WhatsApp and email submission.
Admin panel backed by Supabase — vehicles, drivers, availability tracking.
Price logic per ride type and zone — transparent pricing shown before confirmation.
Every ride links to a Music Ride session — collaborative in-car playlist via QR.

Shared music experience for private rides.
A real-time collaborative music queue for private rides. Passengers scan a QR code, join a session and add songs from YouTube — no login, no app download required. Built as a full-stack React / Node.js application with Socket.IO.
Socket.IO powered — song additions and changes sync instantly across all connected devices.
Search and play any YouTube video. No Spotify API needed — works without any account.
Driver generates a QR at ride start. Passengers join in seconds with any phone browser.
Driver account manages the session — can approve queue, skip, pause and end the session.
System · Internal use
