Fullstack Software Developer & Technical Consultant

Like a mindful architect, I love creating software with focus on quality, sustainability and efficiency.
I gained proven experience with web technologies and distributed systems
with a passion for parallelisation and automatisation.

As a keen developer I am aiming for cleaner code and new challenges with every project.
