Carrier Web App & Integration — USA
A USA customer streamlined shipping with a custom Java Spring Boot web app and unified DHL, FedEx and UPS integration — rate shopping, label generation and tracking in one place.
The story behind the project
Shipping was handled manually across multiple carrier websites, with no single place to compare rates, book or track — slowing the team and scattering shipment data.
We built a custom Java Spring Boot carrier app with unified DHL, FedEx and UPS integration, so the team compares, books, labels and tracks every shipment from one screen.
