Personalized itinerary generation based on budget, trip duration, and interests such as mountains, culture, and food
Functional MVP / Project Detail
Itinerary Orchestration & Cost Modeling Platform
A functional travel-planning MVP for exploring Pakistan, generating personalized itineraries, estimating regional costs, reserving package seats, and managing travel operations.
Functional MVP / Full-stack travel planning platform
Project Overview
This page expands the case-study summary into a clearer view of scope, architecture, workflow, and technical signals.
Stack
Next.js 14, React, TypeScript, Tailwind CSS, NestJS, PostgreSQL, Prisma, REST API
- Destination discovery, personalized multi-day itineraries, regional multi-currency pricing, package reservations, custom-trip registrations, and authenticated travel operations.
- Travel planning information for Pakistan is fragmented across destination websites and manual booking channels. The platform needed to unite research, itinerary creation, cost estimation, package discovery, and registration in one coherent experience.
- Delivered a functional full-stack MVP that combines Pakistan destination discovery, shareable itinerary generation, multi-currency cost modeling, package reservations, custom-trip intake, and authenticated operational management.
Features
Functional Scope
The project scope is framed around real product and operations behavior rather than a surface-level screen list.
Day-by-day destinations, activities, travel guidance, and itemized cost breakdowns
Regional pricing for local, Chinese, and international travelers across PKR, USD, CNY, GBP, AED, SAR, and EUR
Database-backed, shareable itineraries with persistent pricing and exchange-rate snapshots
Curated tour packages with seat availability, package reservations, and custom-trip registration
Authenticated admin workflows for destinations, packages, media galleries, bookings, payment status, and customer requests
Engineering
Technical Signals
These signals show the implementation concerns that matter when a system moves beyond a prototype.
Engineering Signal
Itinerary engine selects destinations from traveler interests and distributes available days across the route
Engineering Signal
Centralized pricing service owns traveler-market rates, currency conversion, service fees, security costs, and display totals
Engineering Signal
Pricing snapshots preserve the market, currency, exchange rate, and calculated totals used at decision time
Engineering Signal
Seat reconciliation keeps package availability aligned when reservations are created or cancelled
Engineering Signal
Prisma relational models connect destinations, itineraries, itinerary days, packages, bookings, and custom-trip registrations
Engineering Signal
DTO validation, structured database-aware errors, file logging, and operational references improve API reliability and traceability
Workflow
How The System Moves
The strongest project pages explain what happens to state as users, admins, workers, and services interact.
- A traveler chooses a budget, trip duration, interests, traveler market, and display currency.
- The itinerary engine selects suitable destinations and distributes the trip days across the route.
- Activities and destination guidance are assembled into a day-by-day plan.
- The pricing service calculates regional rates, conversion, service fees, security costs, and an itemized total.
- The completed itinerary and pricing snapshot are persisted and can be shared.
- Travelers reserve package seats or submit custom-trip requests for admin review and status management.

Problem Statement
Travel planning information for Pakistan is fragmented across destination websites and manual booking channels. The platform needed to unite research, itinerary creation, cost estimation, package discovery, and registration in one coherent experience.
Architecture Overview
Next.js 14, React, TypeScript, and Tailwind CSS power the responsive frontend. A modular NestJS REST API uses Prisma and PostgreSQL for destinations, itinerary days, packages, bookings, custom-trip registrations, and persistent pricing snapshots, with token-based authentication protecting admin operations.
Data Flow Explanation
Budget, duration, and traveler interests feed an itinerary engine that selects destinations and distributes days across the route. A centralized pricing service applies traveler-market rates, currency conversion, service fees, and security costs before persisting the itinerary and its pricing snapshot. Package and custom-trip submissions then enter admin-managed operational workflows.
Engineering Decisions
Itinerary composition, destination content, and pricing rules were separated into explicit domains. Price and exchange-rate inputs are snapshotted so historical totals remain operationally accurate, while booking creation and cancellation reconcile package seats. DTO validation, structured database-aware errors, and references such as PV-ITN-XXXXXX and PV-CTR-XXXXXX make workflows traceable.
Scale & Reliability Considerations
Relational models and a centralized pricing boundary support additional destinations, traveler markets, currencies, and fee rules without duplicating calculations across screens. The MVP currently uses admin authentication and local file-backed media workflows; customer accounts, RBAC, payment-gateway integration, and production cloud image storage remain future enhancements.
Outcome
Delivered a functional full-stack MVP that combines Pakistan destination discovery, shareable itinerary generation, multi-currency cost modeling, package reservations, custom-trip intake, and authenticated operational management.
