Already during my studies I intensively dealt with the .NET stack to realize various projects. After my graduation I used this knowledge in the logistics industry and currently in e-commerce market.

  • Age: 32
  • Degree: B.Sc. Medical Informatics
  • Stack: .NET / C#

To store the data (depending on the use case), we have used document-oriented systems such as MongoDB, RavenDB, and LiteDB in addition to classic relational databases such as MSSQL and MySQL.

Currently, my work topics are mainly about interfaces between microservices using message brokers (Azure Service Bus), as well as REST APIs.

To manage these microservices, administrative topics such as Azure DevOps, Kubernetes, and Terraform are part of the day-to-day work


As described above, I have already used various technologies and tech stacks in past projects. The focus here is definitely on the .NET stack.

.NET Core / EF Core / C#100%
Blazor 80%
HTML / CSS & Javascript 80%
Xamarin / MAUI 70%
Angular 60%
MongoDB 90%
DevOps 75%


Since early years I have been aware that I would like to work in software development. Then, step by step, the hobby became the profession.

Bachelor of Science - Medical Informatics

2014 - 2018

Fachhochschule Dortmund, Germany

In various practical projects I was able to learn C# / .NET independently. In addition, I was able to familiarize myself with other technologies, such as NoSQL databases (MongoDB, RavenDB, OrientDB), in addition to the regular course content. I also had the opportunity to take a look at agile management methods through elective courses.

Practical informatics

2011 - 2014

Fachhochschule Dortmund, Germany

After my school education, I went directly to the FH Dortmund through a cooperation with the Robert Bosch vocational college. While still at school, courses at the university could be attended and completed at the same time.

In 2014, I decided to change my major to medical informatics because the individual courses generated more interest in me.

Apprenticeship: Information technology assistant

2007 - 2011

Robert-Bosch-Berufskolleg Dortmund, Germany

After graduating from secondary school in 2007, I went to the Robert-Bosch-Berufskolleg in Dortmund to do a school-based apprenticeship as an "information technology assistant". During the apprenticeship, I also obtained my entrance qualification for university of applied sciences.

In addition to electrotechnical topics, the training included intensive work with Java, network technology and relational database systems such as MySQL.
