name: implmentation description: when implementing a subproject or a project use this skill

How to implement

• all projects should be in Java 21 and Springboot 3.5.9
• always use a standard file structure, to keep things clear and organized
• always use maven
• if there is a standard spring approach to solve a problem, use that
• be spring idiomatic
• where possible use spring annotations, e.g. @Cacheable
• where relevant use JPA
• prefer text blocks over escaping in strings
• ALWAYS use clean code. Prefer SOLID and DRY and YAGNI
• use Unit Tests to ensure all logic is OK
• use integration tests to show that all works
• in the README.md file, ensure that there are instructions of how to test the system using curl commands
• if there is a need to pass some value from a previous step, ensure that the user can do copy & paste to get the result they need
• where relevant make a docker compose file to start all needed (assume docker is working on the computer)
• have run.sh and test.sh files to run and test the code in each subproject as needed
