About Yoink

Yoink is a startup of a team of professional developers active within the Java ecosystem. We value sustainability, craftmanship, sharing and fun. Constant improvement lies at the heart of what we do.

Yoink sustainability

At Yoink we believe that sustainability should be the driving factor in any new endeavour. This has lead us to put sustainability at the top of our list of values. In every decision we look for the greener path to take. This manifests itself in the clients we invest in, the projects we work on and our choice to transport ourselves sustainably. Where there is no good alternative yet, we compensate potential environmental impact.

Last year's top actions:

Expertise

Yoinkees have a wide range of expertises, in- and outside the Java and Open Source ecosystems.

Sharing

Yoinkees like to share. We believe sharing of knowledge makes the world a better place. You can find us on meetups and conferences, or request an on-site workshop or training.
