After a fantastic ride, it's now time to say goodbye. 3 intensive months of traineeship are over and I would do it again anytime - Java, Spring Boot, React.js CI/CD and Security - packed into 8 weeks of hands-one training followed by a project phase. 

My final project: Find Your Wine - The app recommends the best matching wine(s) based on the information provided. For this, I used freely available datasets and cleaned and merged them with python. Then I stored this data in a MongoDB and implemented a recommendation system in my Spring backend. In the React frontend, users can configure their wine preferences and then select the perfect wine based on the description and match with their details.

What would be the internet without cyber security? To secure my application and to give the possibility  to sign-up and log-in, I'm studying this week Spring Security and the fundamentals of cyber security. 
Therefor I developed and implemented this security-architecture. In the future I'll try to follow a security-by-design approach. 

After building fancy Full Stack Applications with React and Spring Boot and deploying them to the cloud, it's time to handle the data. Therefor I added a MongoDB to my Application. 
Even if my application will never be that big, that I have to worry about scalability, I decided to go with NoSQL. 

While a relational database would have been also a viable option. As is want to work in the future with large datasets and big data analysis, I choose MongoDB. 

Having been heavily involved with Spring / React with full stack app development lately, today I deployed the Dev Quiz app via Docker on Heroku.
What a good feeling when you have gone through the complete development process from start to finish. 

From now on I am working 100% full stack and have built a quiz app. 
This has a Spring Boot backend with Rest:API interface and a React.js frontend. 
In doing so, I tried to consistently follow through with Clean Code and TDD. Also a charming design with styled components may not be missing of course. 
The current status covers only the first two user stories, a verification tool and also a multiplayer with Sockets.io is planned and will be added soon. 

What would be React without React Router? 
Today our App got new Routing features with dynamic routing and conditional rendered pages.
