Helping teams build elegant, robust software. Passionate about clean code, modern Java, and sharing knowledge.
Hi, I'm Patrick. I help teams and developers create clean, maintainable, and modern software. My focus is on Java, Spring, and cloud technologies, but above all, on people and learning together.
I love sharing knowledge, experimenting with new ideas, and making complex topics accessible. Whether through coaching, training, or speaking, my goal is to empower others to grow and succeed.
At 42talents, I work with teams to build modern, maintainable software. My focus is on clean code, effective collaboration, and practical solutions using Java, Spring, and cloud technologies.
I teach and develop courses on software engineering, Java, JavaScript, and agile methods for students at the Zurich University of Applied Sciences. My goal: make real-world software skills accessible and inspiring.
As a board member, I help shape the Swiss Java community - organizing events, supporting knowledge sharing, and connecting developers across Switzerland.
I help organize SoCraTes Switzerland, an open-space conference for passionate software crafters to connect, learn, and experiment together.
I co-organize Voxxed Days Zürich, a conference that brings together developers and tech enthusiasts to learn, share, and grow as a community.
I co-host the Software Crafters Zurich Meetup, where we practice, discuss, and grow our skills through hands-on sessions and open discussions.
I bring together the Swiss agile community through events and initiatives that promote Lean, Agile, and Scrum practices.
As a certified instructor, I deliver hands-on training in Spring and VMware technologies - helping teams master modern development tools and practices.
