This is a demo application. Technologies used here demonstrate my working proficiency as a full-stack developer.

Short list of goals of this demo is described on dashboard. Application is focused on viewing a predefined list of coffee items that are fetched from Elasticsearch. This list can be searched using search bar on efficient way. Idea is to demonstrate full-text search capabilities in PostgreSQL and efficient search approach using search engine noSQL database - Elasticsearch. When you look at the graphical interface you should see a decent design and good user experiance ( good UI + UX ).

This application is secure , ordering a coffee can't be made by just anyone. Spring Security is used with JWT token authentification.

Also all stuff that is being made in application is being tracked ( Entities are audited, user activities are being tracked ). Database is filled and initialized with predefined data to demonstrate my knowledge of SQL. Also since I'm using JPA I want to demonstrate that I know how to use JPA with Spring. Application is filled with data of few types of coffee. PostgreSQL is filled first with data than all coffee items are reindex only once to Elasticsearch for simplicity sake( there is no reindex endpoint implemented at this point, once at startup Coffee documents are created ).

There are few types of users in application:

• ADMIN
• ENGINEER
• BAD_MANAGER

They all have their privileges. Some can drink coffee while others can't. Some of them can't even ask for coffee.
