Portfolio

Hello!

My name is Theis Gaedigk and I am from the beautiful Ruhr area in North-Rhine-Westphalia in Germany and currently attend the 11th grade of a comprehensive school.

I also have hosted various applications on my servers. You can see and visit all of them on my status site: https://status.the1s.de.

Here is my self-hosted gitea, there you can see all of my projects/repositories: https://git.the1s.de/explore/repos.

For most of my self programmed applications I have written a Tour/Tutorial, these can you find here.

I am also interested in creating videos and photos. I am mostly creating Instagram Reels for my schools Instagram Account. For those videos I have created a separate portfolio, on my self-hosted Immich.

HIGHLIGHT

Borrow System

08/2025 – now

The Borrow System is a rental system that I have programmed all by myself for my school. It is the biggest project I have worked on so far.

Learn more

The Borrow System consists of two React frontends that access an Express.js backend. This backend stores the data in a (currently) MySQL database. In the future, I will replace this with a PostgreSQL database. There is also an API for the ESP32 located in the physical cabinet containing the items available for loan. (API documentation)

The repository for that can you visit under: https://git.the1s.de/Matthias-Claudius-Schule/borrow-system
