1. README.md: no information on how to run and test the app.
2. README.md: no information on minimum runtime requirements (Java 11+).
3. Unused code: getSurname(), getLoans(), setLoans(...) etc. Best practice: never write/generate code "just in case".
4. Packaging: according to Common Closure Principle, classes that change together must be packaged together. So, instead of putting closely related classes in different packages (exceptions, models, enums, repositories, requests, services), put them together or split by domain (lending, client). More info here.
5. API: the API tries to be, but is not RESTful. E.g. plurals should be used: /loans, /loans/{clientUUID}
6. Architecture: domain model leaks to the API. Instead, we should decouple the domain model from our API/screens, because they change for different reasons. In practice, our APIs should always return DTOs, not entities.

Люди, которых упомянали во время курса

• Kent Beck – создатель eXtreme Programming. У него есть две бомбические книги: "TDD by Example" и "XP Explained."
• Sandi Metz – придумала термин "echo chambers". Написала отличную книгу по ООП "99 Bottles of OOP." Еще стоит посмотреть все ее доклады с конференций.
• Martin Fowler – написал книгу Refactoring и Patterns of Enterprise Application Architecture (PEAA). Вторую следует почитать, если хотите систематизировать знания по классическим паттерам архитектуры enterprise приложений.
• Michael Nygard – написал книгу по
