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

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

In the field of databases, I have been able to build up experience over the years in classic relational databases such as MSSQL and MySQL, but also in document-oriented systems such as MongoDB, RavenDB and LiteDB.

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

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 I had computer science as an elective subject in school and wrote my first lines of source code, it was clear to me that I wanted to work in software development. I knew that I wanted to work in software development. Then, step by step by step, the hobby became a 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.
