We built a complex, 4-sided marketplace for US-based university travel. Our system manages everything from charter flight inventory to automated payment routing and seasonal pricing logic.
The Challenge
The Complexity of Group Travel
Organizing university tours is a logistical nightmare involving four distinct personas: Students, University Heads, Vendors (Flights/Hotels/Catering), and Internal Ops teams. Landmark needed a system that could handle nested inventory and seasonal pricing volatility without manual intervention.
The Engineering Journey
Designing for Scale
We built the entire platform from scratch using FastAPI for the backend and Next.js for a lightning-fast, mobile-friendly frontend. The focus was on creating a Rules Engine that could handle the hundreds of what-if scenarios inherent in travel — such as cancellations, partial refunds, and fluctuating vendor rates.
Key Features
Technical Innovation
4-Way Persona Dashboards
Each user group has a tailored interface. Vendors manage their own inventory (charters/hotels), while students manage their own documentation and payments.
Automated Pricing & Margins
The system automatically calculates business margins based on real-time vendor availability and seasonal peaks.
Financial Orchestration
We integrated sophisticated payment routing that collects funds from students and automatically triggers payouts to multiple vendors while retaining the company's profit.
The Outcome
The Business Impact
Delivered well within the academic cycle, the platform transformed Landmark from a manual, spreadsheet-heavy operation into a high-tech marketplace. The architecture is now primed for the next phase: AI-personalized travel itineraries.
“The Rules Engine was the real intellectual challenge here — travel has hundreds of edge cases. We designed it as a composable rule graph so that Landmark's ops team can add new pricing or refund logic without a single engineer touching the codebase.”
