General

Python as general purpose scripting language: Writing all scripts that helps the developer. Eg, database importer/exporter, tools for building, deploying.

Java 12: Java is well known, not only considering the current core team. It has certainly one of best tooling support. We assume it to be the most popular language for programming modern backend systems.
We decided to wanted to have Jigsaw in place, to start with a pretty modular system even, when staring with monolith. As we want to use the most recent version of Java, that has mature tooling support and works with other libraries/frameworks we want to use, we decided to use version 12 of Java.

Spring Boot: Decided for it’s popularity and it’s fast pathed way of setting up typical backend systems. It relies on the strong foundation of Spring for Dependency Injection and AOP, making it easy to implement enterprise grade systems.
Spring Security: To secure all endpoints
Spring Data Rest: To make the creation of HAL compliant REST endpoints a breeze.

JPA: To map database entities into Java classes. The defacto standard in the Java world.
PostgreSQL: We assume this is the most advanced relational database, that also supports things like Json datatypes and has proven for years, it’s matureness.

JavaScript/HTML/CSS as the main language for the frontend.: We are not sure if we should use Typscript. But HTLM/CSS is out of question.

Spring WebMVC: Use for the server side rendering of page with the help of:
Thymeleaf: As the templating engine
React: Used to deal with user interaction rich parts of the site. For the current MVP, this will be the part were the user enters his profile.
