"Jendrik A. Potyka"

Hi, I'm Jendrik, a software developer from Wuppertal, Germany. You can find me on the internet under the nickname jpotyka. As a teen, computer games inspired me to dive into C++ to create my own games. Luckily, my school even offered a C++ LEGO robotics class. Through the development of Minecraft server plugins I also came in touch with Java. When I started to study physics, I switched to Python, which I needed for the scientific evaluation of experiments. Currently, I am involved in Python backend and library development, DevOps, DataScience and I am always eager to learn new things. In 2022 I founded the company Digon.IO GmbH with fellow students. Since then I have been working as managing director and software developer. Digon.IO offers individual development of software for applications related to data science to companies. This also includes the development of software tools for engineers and scientists.

Some projects I am working on or have worked on...


A simple in-process python scheduler library with timezone and threading support. Schedules tasks by their time cycles, fixed times, weekdays, dates, weights, offsets and execution counts and automate Jobs. View repository...


A role-based access control (RBAC) permission library for python. View repository...


An image registration library for python including a simple interface for building new models. Currently two image registration models for linear transformations based on scikit have been implemented as part of a toolchain in the context of particle image velocimetry (PIV). View repository...
