AI Development

These projects explore building applications with the Claude API. They form a full-stack demo: a Java/Spring Boot backend and a React frontend that together provide a working CRUD application built with AI-assisted development.

• claude-java-demo

  A Spring Boot REST API built with a hexagonal (ports & adapters) architecture. Manages Products and Customers via full CRUD endpoints and exposes interactive API documentation through Swagger UI. Uses MySQL in production and H2 for testing, with Docker Compose for local orchestration.

  • Java 17, Spring Boot, Spring Data JPA, Maven
  • Hexagonal architecture — domain layer has zero Spring coupling
  • 49 tests across domain, application, controller, and persistence layers
  • Dockerized with multi-stage build and health checks

• claude-react-demo

  A React 18 single-page application that serves as the frontend for claude-java-demo. Provides a tab-based interface for managing Products and Customers with create, list, and delete operations. Communicates with the backend via a centralized REST API client.

  • React 18, Vite, native fetch API
  • No external UI component libraries — hand-written CSS
  • Backend URL configurable at runtime via environment variable
  • Dockerized with multi-stage build served via nginx
