I've had the pleasure of working with Patrick on my team, building a new CRM system from scratch, during my time as his product owner.

In the year we worked together, he showed that he is not only a great developer and sparring partner but is able to bridge the gap between the technical and business teams very well. He is able to explain complex technical topics simply to business stakeholders and, on the other hand, can translate business requirements into technical solutions effectively. He thinks through topics from a customer-centric and end-to-end perspective and was able to support business stakeholders significantly by jointly conceptualizing, analyzing, and challenging features in the early stages, thus smoothing the path all the way into development and production.

If you are looking for a developer with excellent knowledge of not only software development and architecture but also requirements engineering and product design, you can stop searching. He is the right guy and I can recommend Patrick unconditionally!

I had the pleasure of working with Patrick on a client project for one of Germany's biggest eCom companies. Patrick combines a precise analytic mind with strong software craftsmanship.

He has proven himself very valuable plenty of times in the project, analyzing even the hardest issues and providing a proper solution, while maintaining a very high standard of code quality. Also mentionable is his attitude to not polluting the business code with workarounds and keeping the business code well-tested at any time.

I can recommend him without any hesitation to anyone searching for a business analyst or cloud consultant on the highest level.

Reliable, organized, effective, and intelligent!

I'm the co-founder of Bienformatik e.V., a non-profit organization in the southwest of Germany. We contracted Patrick to build our very first Android app to educate the public about the importance of bees in our ecosystem as part of a state-run horticulture fair. Patrick played a significant role in realizing our needs and developed multiple iterations of the app. Discussing product features in our regular workshops always was a joy, and Patrick accurately developed the pre-communicated solutions while working with backend developers.

Thanks to Patrick's good organization and reliability on timelines, we were quickly able to show our progress to stakeholders and ensure we were on track. Although the horticulture fair is over, we still actively use the app years later, where it is easing our work on keeping track of the biodiversity across the region and making an impact on regional development. Whenever you need someone to tackle various problems on a strict timeline, Patrick is the solution to your problems.

Over the past five years, I have worked with Patrick on numerous occasions. From joint projects at the same firm, spending hours in sparring sessions helping each other to working as a freelancer for one of his startups.

Having initially met at a training session at T-Systems International, we quickly connected and found ourselves working on multiple projects shortly afterward. Throughout our shared time there, we were able to help each other with various problems, and Patrick was always known for looking at them from different angles and offering creative solutions with exceptional outside-the-box thinking.

Patrick is very good at quickly grasping complex problems and breaking them down into simple blocks. After we parted ways at T-Systems, we took different paths but found ourselves working together soon after when I was hired as a web developer at his first startup.

Patrick has an incredible breadth of knowledge not only in the technical domain but also in his approach to building systems, products, and companies. He is one of my first choices for brainstorming ideas, and I can assure you that Patrick is a highly valuable addition to any team!
