A selected list of projects I have worked on. From open source work and personal projects to building companies.

Future Packaging Forum

July 2020 - August 2020

I joined the futurpackaingforum as the first person with a deep product and technological expertise, the goal was to build a business around sustainable packaging. During my short stay I contributed a detailed business model using google sheets and monte carlo simulations and a significant portion of the pitch deck. I also conceptualized products variations that are easier to test and to build.


June 2020 - ongoing

Sharing and discovering new content is an essential part of how the internet works. The recent years however seemed to have pushed us in direction of SEO optimized webpages trying to market products. Original content seems to have a hard time ranking high enough in traditional search engines. is a toy project that explores this misalignment.


April 2020 - June 2020

DiversifyNow is a volunteer initiative and the result of a design thinking project from March 2020 to May 2020, we wanted to get to the bottom of an important societal question to which we have not been able to find a satisfactory answer to date:

“Why are there still mainly white men in German management positions today?”

And above all, how can we promote diversity in companies and support others in doing so?


fewture - small help, big impact

February 2020 - April 2020

We make donating to various fundraisers as easy as buying an app in the App Store or matching someone on Tinder.

Therefore we unite the biggest and most trusted fund raisers and offer them a platform to raise awareness with young target groups and generate more donations and data insights. We combine state of the art technology, gamification, and rich content updates for all projects to increase user engagement.


APX - Mentoring and AMA Offices Hours

May 2019 - ongoing

At APX I mentor and share my experience with startups. This usually evolves around an all day mentoring event held every 3 Months. There I get to meet 3 - 4 different startups asking questions and picking brains of the mentors. Questions range from high level go to market strategy down to technical questions and or brain storming. It’s up to the startups to make the most out of their time. Apart from that I infrequently visit the APX Offices doing “ask me anything” session with startups.


telstar - Producers and consumers for redis streams

June 2019

This library is what came out of creating a distributed service architecture for one of our products. Telstar makes it easy to write consumer groups and producers against redis streams. In order to run our distributed architecture at @bitspark we needed a way to receive and produces messages with an exactly once delivery design. We think that, by packing up our assumptions into a separate library we can make it easy for other services to adhere to our initial design and/or comply to future changes.


bitspark - Narrowing the gap between human thinking and computer language

November 2018 - February 2020

Programming today requires a shift in thinking. This makes it hard to learn how to write programs. On top of that, IT experts often use a language which is difficult to understand for non technicians. At we develop Slang which aims to make programming easier, faster and more comfortable. It avoids coding, repetition and frustration.

images/easytainer.png - Simpler docker platform

January 2018 - April 2018

Easytainer is/was a serverless docker platform that runs docker images in response to HTTP requests. It had a neat cli that allowed easy management of the deployed endpoints. You could run any docker image and the stdout was streamed back to the client.


lace - .dotfile management

March 2014 - ongoing

Logging in to different machines at work or at home and using the same .dotfiles on them. Bootstrap a new machine, even if they are differently flavored. Updating .dotfiles should be a breeze as well as sharing common .dotfiles with your teammates by just installing them next to your own .dotfiles. Lace drew inspiration from brew.


Wholelottalight - Art Degree Project

February 2014

I built a chrome extension for a friend’s BA Design and Art Degree project. The extension would take the current url and forward it to a locally running server that performed a IP to Lat/Lng lookup. The coordinates would then be displayed on a 16x2 LCD display connected to an Arduino.


February 2011 - ongoing

As a freelancer I built a web based image archive software for a client. Using several state of the art tools to fulfil the functional specifications which where presented to me. A cascading category based navigation, a lightbox based cart, a live translation tool and a drag and drop image uploader. Moreover there is a full blown admin interface to manage all aspects of the application.


Sorting Algorithm Visualization

June 2011

In the seminar phase of the BOS technology I enrolled for a Java project without any prior knowledge. After a short introduction each participant could set his own project goal. I decided to visualize sorting algorithms. The algorithms are implemented with the decorator pattern and thus are step-synchronized which provides a nice to look at visual feedback.


October 2008 - February 2009

Inspired by friendfeed we took the concept and adapted it to the German market and eventually sold to Mr.Wong The application was written in Ruby on Rail 2.0 with together with a background processing queue that pulled in the content from all the linked services.


January 2008 - October 2010

Over the course of 10 months we rewrote a large portion of the web application at so it would resemble a modern MVC app more closely. Together we redid the Database-Abstraction-Layer, reimplemented all the affected controllers and wrote a new template parser. Being done with that we designed an applied a more effective way of organizing files inside the project.
