## Overview

Delivery Tech is a Spring Boot REST API. Its documented live workflow is a client calling monitoring or application-information endpoints; the repository also contains customer and order service flows, including order creation, lookup, status changes, and cancellation. These flows use DTOs, domain entities, services, and Spring Data repositories. The README documents H2/JPA persistence, but the sampled excerpts do not show application startup wiring or repository-to-database configuration; those relationships are therefore documented rather than inferred from imports.
