05 — For Limo & Chauffeur Operators

Your fleet, live on one screen.

Most chauffeur operators still run dispatch on WhatsApp groups, paper sheets, and prayer. This is the live system Five Star Chauffeur runs in Miami today — every car, every status, every VIP, in one place.

  • Know where every car is, right now. No more "let me check with the driver."
  • Assign a driver in two taps. Skip the WhatsApp ping-pong.
  • Catch a flight delay before the client does. Flight tracking on every airport ride.
  • Hand off the night shift without losing context. Same board, dark mode, full ride history.
  • See revenue, VIPs, and late-risk at a glance. Stop opening four tabs.

05 — About

Hi, I'm Denis.

Brazilian developer based in Miami. I build React Native apps and modern websites — from MVP to launch — for founders who want to move fast without losing quality.

I've shipped event ticketing platforms, luxury transportation tech, and bilingual business sites for clients across the US. I work solo, communicate clearly, and deliver complete packages — not half-finished prototypes.

  • 📍 Based in Miami, FL
  • 🌐 Trilingual: English, Spanish, Portuguese
  • 🚀 Solo operator — you talk directly to the builder
