■Languages used
Kotlin / Javalin
They use Kotlin and Javalin because they are powerful in that they allow developers to focus on the business logic, eliminating the redundant writing style of Java, while taking advantage of Java's rich library set.
Javalin is also a lightweight framework that allows us to check all sources when a problem occurs, making it easier to separate whether the problem is with the application or the framework.

React / Recoil
They use React because of its reusability due to componentization and good visibility due to separation of responsibilities.
In particular, the separation of business logic through the introduction of Hooks has produced an efficient division of labor, and they have adopted it because they believe it is suitable for this team.
