For 21+ years I've helped tech teams turn developer & customer intelligence into product strategy, grounded in cognitive psychology and a habit of testing my assumptions. I help build communities, and the teams that run them.
I lean on two things that don't always sit together: a cognitive-psychology read on how developers and customers actually behave, and an experimentation
habit (those 500+ A/B tests at Randstad & JDE) to check what works instead of guessing. I'm
still learning, mostly in the open.
Cognitive psychology
Why developers and customers actually behave the way they do.
Business experimentation
500+ A/B tests at Randstad & JDE. Measure what matters, prove what works.
Community building
Helped grow the Joomla!, Magento, CRO.CAFE and Spryker communities.
(AI) automation
Reliable AI workflows and local-first tooling that earns its keep.
Guido has a rare ability to translate community insights into tangible business intelligence, and to bring the business closer to the community.
