About me
My name is Kilian and I am 25 years old and come from Lower Franconia, Würzburg. I study computer science and have been working as a student trainee for several years.
This homepage tells something about my skills, projects and hobbies.
You can consider the things listed here as a kind of portfolio, whereas especially the page about the terrarium should be more of a guide to reproduce or inspire.
I welcome comments on the respective project, no matter if questions, criticism or own experiences.
Have fun browsing!
My passion for programming I discovered at the age of 15/16 and started to learn with a C++ book. Shortly after that I got involved in native Android app development, and later I started working with Xamarin (C#) cross-platform. In addition I also learned the basics of WPF (C# and .Net) development and did some work on the Azure Cloud. Currently I'm writing native Android apps with Java/Kotlin and getting familiar with Flutter.
My spare time is not only programming, of course. I work on my home automation with Home Assistant and go to the standard dance.

Education
OCT2018 — TODAY
University of Applied Science Fulda
Bachelor of Applied Science
University of Applied Sciences Studies
In 2018 I started my computer science studies from Scratch at the University of Applied Sciences Fulda with many practice oriented subjects.
- Practical projects with the latest technology (FlyMusic)
- Git versioning, Regex, Databases, Scrum
- Many programming languages (Java, C, C++, ...) and web development (Html, Css, PHP, JS)
- Good optional subjects in all directions (Android programming, robotics, ...)
OCT 2016 — SEP2018
University of Würzburg
Bachelor of Applied Science
University Studies
Here I started my computer science studies, because Würzburg is my hometown. Since I started working as a student worker in the 2nd semester, I soon realized that the pure university study does not offer me enough practical relevance.
Experience
MAR2019 — TODAY
Fleetboard Logistics GmbH
Student Worker – App Development
Current job
Here I continue to work with my existing and new colleagues at the App HABBL.Since I learned a lot of Kotlin in my private projects I was one of the first to use the new language. The advantages of Kotlin include shorter code and null safety.
Everyday tasks
- Scrum and Jira
- Independently find and solve problems
- Communication with team members
Entry into the world of work
I started this job as a student worker during my 2nd semester at the University of Würzburg. HABBL was the project I was working on here.
During this time I gained a lot of practical experience and got to know tools like Git and Jira. But I was also given a lot of freedom, I was allowed to design code myself and implement it independently after consultation and adjustments with my colleagues.
HABBL was later integrated into Fleetboard Logistics GmH : Article, that's where I work at the moment.
