I’m a software engineer.

I’m a young, yet experienced software engineer who finished his master’s degree in computer science in 2018. Since that year I work for HMG Systems Engineering to develop innovative healthcare software that helps patients to get the best fitting drug at the proper dosage based on their individual genetic properties.

I’m also a big supporter of free/open source software and always made my personal code publicly available if I considered it to be helpful to others. You can see some of my projects and code contributions here and on GitHub .

Professional experience ¶

Projects ¶

Here is a collection of some of the bigger projects I worked on in the past, either as part of my computer science studies or in my free time.

Some background information first: The site you are seeing right now was built with Hugo, a static site generator. I wanted to showcase my photographs, and so I was looking for a nice-looking, feature-rich gallery. Unfortunately there was nothing suitable available for Hugo.

So I started implementing a solution by myself. I named it hugo shortcode gallery. It provides a special shortcode, using Hugo’s module mechanism. With this shortcode, a gallery can be placed at any place in a content-providing markdown file. It uses Justified Gallery to display all images row by row and Swipebox to display one image at a time in full size. On top of that, a simple-to-configure filtering system is integrated, which allows the user to select a subset of the images as visible.

You can find it on Github , where it already has over 300 stars.

This project provides the ability to use Hantek 1008 USB oscilloscopes without the proprietary software. It works on Linux and Windows. You can include a provided class in your project to get (high- or low-level) access to the features of the device. As an alternative, you can use a command-line tool to gain data from the USB oscilloscope saved into a CSV file. You can find it on Github .

This software was one of the results of my master thesis. In which I, amongst other things, reverse engineered the USB protocol of the Hantek 1008 device with the help of Wireshark.

A mobile puzzle game for Android (Get it )

Connect 5 is taking the classic Connect 4 to the next level. Similarly to the original, the goal in this game is to build a row of 5 connected tiles, either horizontally, vertically or diagonally without giving the opponent the opportunity to impede or do the same. The clue in this game is that the board is potentially unlimited in size and will ever expend while you are playing (you can only put a tile next to an already placed one, whilst unlocking new locations for yourself and your opponent).

Features: Simple Singleplayer, Local Party-Mode to play against friends, Multiplayer to challenge people all around the world and get #1 in the rankings.

I worked on this together with a good friend and fellow student during the early semesters of our bachelor studies. I implemented most parts of the frontend and he implemented the backend, which is a plain Java server.

Developed for my bachelor thesis, this GUI software runs on a Raspberry Pi mini computer with a connected 8" screen. Its use is to graphically display different live measured values (e.g. voltage and power of a solar panel) put into context with weather data in real time.

The goal of this software project was to provide a simple storage API for devices collecting data like weather stations. Devices get an API key and can then push their data as JSON arrays via HTTP posts. Arbitrary data types (like temperature, humidity, …) can be defined. In addition, a simple to use, but powerful query API for authorized users is provided. The users, devices and defined data types are managed with a Bootstrap + AngularJS powered web interface.
