Summary of Changes

Hello @incizm, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on containerizing the backend service using Docker and providing a docker-compose.yml file to manage both the backend and frontend services together. This significantly simplifies the project's setup and execution by leveraging container orchestration.

Highlights

• Backend Dockerization: I've added a Dockerfile for the backend service, enabling it to be built and run within a container.
• Docker Compose Setup: I've introduced a docker-compose.yml file to orchestrate both the backend and a placeholder frontend service, simplifying the setup and running process for the entire application.
• Documentation Updates: The README has been updated to reflect the new Docker-based workflow, removing manual installation steps and directing users to use docker compose up.
