    Katharina Stief⁠

    Group Manager Data Engineering (DE, Marc O'Polo)

    Max was part of our team from July to October and provided outstanding support in optimizing our Open Source Lakehouse Platform. He has a very good understanding of cloud infrastructure in the data domain and truly impressed us with his technical know-how and his ability to quickly find solutions for complex problems. Thanks to his help, we were able to make important progress in our project and significantly improve our platform. I look forward to working with him again.

    Dr. Axel Berger⁠

    Product Owner ML Platform and Services (DE, Porsche)

    Max joined my former team as a software engineer and consultant. Despite the complexity of the existing service landscape, Max familiarized himself with the existing infrastructure very quickly and was a big asset to the team - not only from a technical but also from a personal perspective. What really impressed me was his talent for rapid implementation while keeping code quality and raising the technical bar of the team. I consider him as an expert when it comes to AWS services. I can highly recommend Max to any team that wants to push its product roadmap forward. Thanks Max for your contributions!

    Dr. Mathew Divine⁠

    Head of Digital Lab in Clinical Development & Operations (DE, Boehringer Ingelheim)

    Max is an exceptionally skilled backend developer with expertise in cloud development, DevOps, machine learning, and Generative AI. His proficiency in Python, JavaScript, and Bash makes him a versatile asset to our team. His proactive approach, excellent communication skills, and ability to interact well with colleagues are more than commendable. Max's impressive skills were evident from our first meeting during his job interview. Beyond his technical skills, Max's online content on software development practices and self-employment offers valuable insights. Max is truly a unicorn in his field. Thank you, Max, for your exceptional contributions.

    Sam Klingner⁠

    Head of Data & Analytics (DE, Hubert Burda Media)

    Not many people have the ability to go from paper to productive data pipeline code in less than a week and fewer still where they are relative latecomers to a brown-fields project in need of renewal, Max is one of these people. I’ve worked with Max over the past year as he worked with us on our core data infrastructure as a contractor with little supervision. He has been a remarkable and valued team member and resource throughout the entirety of that time, providing astute research, clever solutions to problems both large and small. In terms of skills, whether it’s Kubernetes, AWS or Databricks and Python he has been able to execute efficiently and with great results. I’d be more than happy to work with him again.

    Bastian Pieper⁠

    Chief Product & Technology Officer (DE, Wemolo)

    Max is a real value to your team. During our time as a co-founders I learned a lot from him. He is a very creative person and has great problem solving skills. He is able to move very quickly and come to a solution fast. Especially in a startup environment where you need to act under high pressure his skills were very valuable. Next to his technical skills I can say that Max is honest, humble and good human being. If you have the chance to meet or work with him please do so. I can recommend him whole heartedly.

    Tomasz Sokolowski⁠

    Senior Data / Software / Cloud Engineer (Freelancer)

    I have had an undoubtful pleasure to work with Max over the course of couple of months on a project for a client from pharmaceutical industry and it has been a remarkable and unique experience. Although I met some extrodinary engineers over the course of 15+ years of my professional career - which Max definitely is - I rarely stumble upon someone who is so laser-focused on delivering maximum business value in the least amount of time while ensuring quality of engineering work. Whatever you throw at Max you can be sure he will get this done, and done fast. But aside from all things engineering, Max is a genuinely amazing human being: humble, open-minded, friendly, sociable and spiritually aware. I hope our engineering paths will cross again some day.
