Containerized backend demos

Small multi-stack backend demos used to exercise container builds and deployment pipelines.

Why it exists

The useful question in these repositories is not whether a sample endpoint works once, but whether the same service can be built, packaged, and published repeatedly.

What I use them to check

• How Go, Spring, and Spring Boot services differ at the container boundary.
• Whether CI/CD image builds stay understandable across stacks.
• Which deployment assumptions belong in a reusable example and which should remain application-specific.
