The goal is to design and implement a logistics aggregator that consolidates multiple shipping carriers behind a single, coherent interface. I need an end-to-end solution: gathering carrier API documentation, defining a unified data model, building the integration layer, and wrapping it with a clean dashboard plus publicly documented REST endpoints. A minimal viable product should be deployable to a cloud environment of your choice and come with installation notes so I can reproduce the setup. Please outline in your proposal: • the technology stack you recommend for both back-end and front-end • how you plan to structure carrier adapters so new providers can be plugged in later • an estimated timeline broken into milestones with the deliverable attached to each The completed project must ship with: • source code in a private Git repository • concise technical documentation (architecture diagram, API reference, and setup guide) • a running demo instance I can access for acceptance testing Clean, well-commented code and clear communication throughout the build will be essential for a smooth hand-over.
