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.
If you are enjoying a tool someone else is building by themselves or with a small team: tell them you like it (and maybe even provide some feedback)
Hardly anyone does and I promise: you'll make their day! 🫶
My most satisfying accomplishment of the day is that I sprayed a small amount of WD40 into a noisy fan which completely took care of the noise.
How is your day going? 😅

@marque.at when transferring domains, after the order has been placed but before it's all confirmed, it would be nice to see those domains in /dashboard/domains (and maybe even /dashboard) with something like a "pending" label/status
Are you living in The Netherlands 🇳🇱 and working on/with atproto things?
LMK and I'll add you to the DutchProto group and you'll be the first to know about upcoming meetups!
Note that you don't need to be able to speak Dutch BTW, English or Dunglish will do 😅
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.
