Overview TravelOS ERP is a high-concurrency

Overview

TravelOS ERP is a high-concurrency fleet management and seat reservation engine engineered for intercity tour and transit operators to handle real-time dispatch, route synchronization, and instant ticketing.

The Problem

During peak booking windows and flash sales, simultaneous customer checkouts frequently triggered double-booking race conditions. Additionally, high database lock contention degraded dispatch dashboard performance and caused live manifest sync failures across remote driver terminals.

The Solution & Architecture

Distributed Concurrency Control: Implemented atomic seat reservation locks using Redis Mutex with strict TTL expiration, eliminating 100% of double-booking races under concurrent load.

Real-Time Passenger Manifest Sync: Architected bi-directional WebSocket pipelines to instantly synchronize seat statuses, passenger check-ins, and driver dispatch states with sub-35ms latency.

Relational Data Integrity: Designed normalized PostgreSQL schemas with Prisma ORM and multi-tenant isolation, ensuring seamless handling of routes, vehicle maintenance logs, and financial reconciliations.

Key Impact & Metrics

0% Double-Booking Incidents under 1,000+ simultaneous checkout requests.

< 35ms Lock Sync Latency across passenger and operator terminals.

100,000+ Manifest Records processed daily with sub-second query execution.
