    Tamer Chowdhury

    Senior Manager, Global Clinical Development & Operations (Pharmaceutical Company)

    I whole heartedly recommend Max from his role as a backend Software Engineer at Boehringer Ingelheim, where he contributed to our project combining Data Engineering, Machine Learning, AWS Infrastructure, and DevOps. He has been a T-shaped strength contributor making significant impact to all areas above. Max demonstrated a valuable ability to balance high-level strategic thinking with hands-on implementation. His agile approach consistently resulted in effective, modern solutions that exactly met our project needs. He approached challenges with a problem-solving mindset, focusing on delivering practical business value. I recommend Max for roles in software engineering, particularly those involving advanced Cloud and Data technologies and methodologies. His combination of technical skills and a results-oriented approach would be an asset to any organization.

    Dr. Axel Berger

    Product Owner ML Platform and Services (Automotive OEM)

    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 and have a very likable colleague. Thanks Max for your contributions!

    Sam Klingner

    Head of Data & Analytics (Large Media Company)

    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 & helping us developing best practices for data operations. In terms of skills, whether it’s Kubernetes and 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.

    Dr. Mathew Divine

    Head of Digital Lab in Clinical Development & Operations (Pharmaceutical Company)

    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. His proficiency with co-pilot coding, demonstrated by accomplishing in 20 minutes what takes other senior developers days, set a new hiring standard for me. 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.

    Bastian Pieper

    Founder & CPTO (Parking Industry Startup)

    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.
