Custom Taxi App & Ride-Hailing Software

Geospatial matching engines, real-time dispatch systems, and fleet operations software engineered for sub-second responsiveness and extreme reliability under peak load.

On-Demand Mobility Engineered from First Principles

Building a ride-hailing or on-demand delivery app is an exercise in high-concurrency systems design. It requires coordinating multiple state machines, processing continuous location updates, and scaling databases to handle surge demand without degradation. At TESARK, we don't build generic templates; we design and implement custom, production-grade mobility systems from the ground up. Whether it is a regional taxi network competing with industry giants or a corporate dispatch system with complex billing, we deliver robust architectures that scale. Our engineering work on Utoo Cabs stands as a testament: 87 data models, a geospatial zone-pricing engine, and a decoupled multi-database structure designed to handle thousands of concurrent driver GPS updates seamlessly.

Core Capabilities

  • Geospatial Matching Engine: Custom matching logic that queries available drivers within configurable radius boundaries, ranking them by estimated arrival time, vehicle type, and historical acceptance rates within seconds.
  • Multi-Database Location Tracking: Decoupled database architecture separating high-frequency location pings (GPS updates every 3 seconds) from core business queries to ensure sub-second read performance on active bookings.
  • Dynamic Geofenced Zone Pricing: Geofenced polygon coordinates mapping custom fare rules (base fare, distance fare, time-slice rates, night surcharges, and local tax structures) dynamically per sub-region.
  • Fleet Operations & Yard Management: Comprehensive fleet dashboards tracking vehicle check-in/out schedules, fuel logging, maintenance warnings, driver-to-vehicle mapping history, and corporate billing profiles.

Frequently Asked Questions

Should we buy a white-label taxi script or build a custom app?
White-label scripts are templates that break at scale. They usually run on monoliths that cannot handle constant GPS pings (e.g. 4,000 drivers pinging every 3s means 80,000 writes/minute). Custom development gives you absolute source code ownership, a decoupled scalable database, customized matching logic, and direct compliance integrations tailored to your specific market.
How do you handle real-time GPS tracking and map updates?
We implement WebSocket connections between driver apps and the server, backed by a high-frequency cache layer (like Redis) and a dedicated location tracking database (like MongoDB or PostGIS). This prevents location updates from overloading the core booking and payment database, keeping the map fluid at any scale.
Can we integrate corporate billing and customized regional taxes?
Yes. Our billing engine handles complex invoicing rules, including base fares, distance thresholds, night surcharges, custom promo code structures with caps, wallet balances, and localized GST or other regional tax configurations. It exports files (PDF, XLS) asynchronously to ensure zero impact on active booking threads.
What compliance and payment integrations do you support?
We have deep experience integrating government KYC services (like Aadhaar biometric OTP/fingerprint verification in India), SMS bridges (MSG91, Twilio), push notifications (FCM), and payment gateways (Paytm, Freecharge, Stripe Connect for split payouts). All security parameters, checksum signing, and refund transactions are handled via custom-implemented backend logic for maximum security.
