Case Study 01 Travel-Tech & Distribution Shipped to Production

Omnichannel Travel-Tech Booking Engine & OCR Infrastructure

Engineered for high-volume travel operators to eliminate fragmented spreadsheets, automate airline & hotel distribution APIs, and process complex multi-passenger bookings with automated OCR passport extraction.

Next.js 14 (App Router) Expo / React Native Supabase SSR (PostgreSQL RLS) Python GDS/Aggregator Microservices Passport OCR (MRZ + Vision)
THE BOTTLENECKS

Legacy Monoliths & Manual Inefficiency

  • Manual copy-pasting of passenger passport numbers causing typo penalties on airline tickets.
  • Slow, un-cached GDS rate queries taking 8+ seconds per search.
  • Disconnected mobile and agency back-office states leading to double-booked allocations.
  • Lack of real-time margin rules and dynamic currency conversion.
THE ARCHITECTURE

Distributed Cloud & Real-Time Sync

  • Fast Next.js 14 SSR frontend with edge caching delivering sub-2s search results.
  • Asynchronous Python microservice pipeline for instant passport MRZ extraction.
  • Row-Level Security (RLS) ensuring strict isolation between B2C, agencies, and operators.
  • Multi-tier quote engine with automated PDF voucher and receipt generation.
System Topology

Engineered Components & Data Flow

LAYER 01

Client Interfaces

Next.js 14 B2C booking portal, cross-platform Expo mobile app, and staff back-office manager.

LAYER 02

API Gateway & Cache

Upstash Redis queue, rate limiter, and edge cache preventing redundant 3rd-party provider hits.

LAYER 03

Processing Workers

Python OCR microservices (MRZ parsing, passport face detection) + dynamic margin compute.

LAYER 04

Data & RLS Store

PostgreSQL 16 with Row-Level Security, multi-tenant schemas, and automated S3 backup vaults.

Core Modules

Engineered Capabilities

⚡️

Instant Multi-Carrier Search

Aggregates multiple flight and accommodation suppliers simultaneously, deduplicating itineraries and normalizing results into a single unified JSON schema.

📷

Zero-Error Passport Ingestion

Machine-readable zone (MRZ) optical character recognition extracts nationality, passport numbers, and expiry dates in < 800ms with automated checksum validation.

📈

Dynamic Margin & Commission Rules

Hierarchical margin engine applying real-time markup percentages, fixed surcharges, seasonal discounts, and multi-currency exchange rates automatically.

📄

Automated PDF Vouchers & Invoicing

Server-side headless document rendering generates branded flight tickets, booking confirmations, hotel vouchers, and compliant invoices immediately upon checkout.
