    Head of Engineering, Interhyp Gruppe: You'll notice very fast that Andre is more than a regular software engineer/architect. Next to his technical skills, Andre has a unique radar for his environment, the people he is working with, and the situation in his and other teams. He also integrates into new teams easily. He acted as a speaker for all the engineers, which he could only do because a) the engineers trusted him and told him their opinion and b) he dared to ask questions in front of everyone when other people remained silent. Besides that, he wants to create software with a business impact. To achieve that he speaks with the users, who are using the software he writes. He does this proactively and without being asked. Andre combines technical skills with "soft skills" in a way you rarely find. It was a pleasure working with Andre. Everyone can be glad to have him on his team.

  • Anna J. McDougall

    Software Engineering Manager, HelloBetter: Andre and I first worked together at Novatec, where he helped my team develop skills in frontend technologies and consulted on best practices for code compartmentalisation. Since then, he and I have both been involved in the local Leipzig React meetup, and I've had a chance to see him give several presentations and workshops highlighting his expertise. Andre is one of those rare engineers who not only manages to deliver and advocate for performant coding practices, but also is able to create great vibes and good culture in engineering teams with his strong focus on community building and supporting others to improve. He does not come at problems with an ego, but instead remains open to different ideas, and also does not judge those with fewer skills who come to him for assistance. Any engineer or engineering team would be safe in his capable hands, both in terms of quality code delivery and personal growth.

  • Timo Freiberg

    Senior Software Engineer, Fastly: I loved working with Andre. He's a great engineer, quick at learning advanced language and backend concepts and always interested in new things. He's also always motivated to improve things, from technical and design to product and culture. I've never seen someone create such a rapport with their coworkers so quickly, inspiring his team and contributing to the company culture. I would love to find a place that fits both our interests to be able to work with Andre again.
