We read small github repositories, and try to understand the code and what design decisions were behind it.

Here is a list of such small Java apps, you can add your own to it: - https://gitlab.com/burak-dev/url-shortener - https://github.com/harismuneer/Library-Management-System-JAVA - https://github.com/ebarlas/microhttp - https://github.com/bowbahdoe/json - https://github.com/bowbahdoe/regex-router - https://github.com/joel-jeremy/externalized-properties - https://github.com/joel-jeremy/deezpatch

Together, we’ll:

• Read and understand the code
• Discuss the architectural decisions/its design
• Write some Architecture Decision Records (ADRs)
• Draw a class diagram and some C4 diargrams
• Decide what testing strategy the repo should have
• Discuss pros and cons of the current implementation

It’s a great way to sharpen your architecture skills and see how others design and structure their systems.

No prep needed — just bring your curiosity and your intuition.
