Open source
Embabel workflow visualizer, Spring Boot auto-configuration optimizer, distroless buildpack builders, and code examples from public talks – all on GitHub.
Teaching
Two lecturers at two Swiss universities of applied sciences: Patrick has taught software engineering at ZHAW since 2013; Thorben lectures at HSLU Lucerne, where he created the Enterprise Programming Lab. Patrick has delivered more than 200 industry workshops. Daniele has taught Spring since the SpringSource era and holds instructor credentials from VMware.
The team
Our core team delivers the work. When an engagement needs another specialist, we add the relevant expertise from a trusted network and make responsibilities explicit.

Our Values
We care about people, code, and outcomes. Our values shape how we work with you and the community: openly, directly, and hands-on.
-
Productive Partnerships
We work closely with you, keep feedback cycles short, and focus on what matters. Great outcomes come from real collaboration.
-
Software Craft
We build maintainable software and help teams sharpen their skills. Clear design, useful tools, and continuous learning guide the work.
-
Communication
We keep things clear and direct. Good communication means fewer surprises and better outcomes for everyone.
-
End-to-end engineering
We look beyond a single layer while staying deliberately focused on Java, Spring, and the JVM. From architecture to production operations, we take responsibility for the whole engineering outcome.
Our Commitment
We help run the Swiss engineering community, not just participate in it: the JUG Switzerland board, co-organising Voxxed Days Zürich, organising SoCraTes Switzerland, and co-hosting Software Crafters Zurich. Here are the groups and events we are proud to be part of.
Work with us
Whether you need an architecture review, an AI agent shipped, or your team levelled up – book 30 minutes and we will assess whether we are the right people for it.
