Client / context: EOS Taxi
Role: Co-Owner & Architect
Status: Completed

## Outcome

Served 10,000+ rides with 98% customer satisfaction

## Project Overview

EOS Taxi was a startup venture where I co-founded and architected a comprehensive taxi booking platform. The system provided real-time ride booking, driver tracking, payment processing, and fleet management capabilities for both passengers and drivers.

## The Challenge

The local taxi market lacked modern digital solutions:

- **Traditional Booking**: Phone-based booking system was inefficient
- **No Real-time Tracking**: Passengers couldn't track their rides
- **Payment Issues**: Cash-only payments limited convenience
- **Driver Management**: No centralized system for driver coordination
- **Market Competition**: Need to compete with established ride-sharing platforms

## Solution Architecture

## Technical Implementation

### Real-time Features
```javascript
// Real-time ride tracking implementation
const trackRide = (rideId) => {
  socket.on(`ride_${rideId}_update`, (data) => {
    updateDriverLocation(data.location);
    updateETA(data.eta);
    notifyPassenger(data.status);
  });
};

// Driver location updates
const updateDriverLocation = (driverId, location) => {
  io.emit(`driver_${driverId}_location`, {
    lat: location.latitude,
    lng: location.longitude,
    timestamp: Date.now()
  });
};
```

### Payment Processing
