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.
Unsurprisingly, the new @eurosky.social firehose is much faster for @sifa.id to connect to (compared to the standard bsky firehose) and on-par with the @microcosm.blue firehose (as all 3 are on 🇪🇺 Hetzner servers)
Well done team, big wins for atproto independence and decentralization this week! 👏👏👏
atproto'd my website a bit further (beyond the @standard.site integration):
1) added a "Right now" box on the homage that pulls in all kinds of atproto activity like @bsky.app posts, @popfeed.social film ratings, @bookhive.buzz reads, @tangled.org repo's etc.
inspired by @dame.is & @brookie.blog, I set myself up with a nice little dynamic profile picture automation, updating the image (or rather: the background/accessories) based on season / weather / country / holiday.
Overkill? Ooooh yes very much so.
Confusing? Potentially.
Fun? ... I hope so!
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.
Svitlana Kulynych Head of Learning Experience, Spryker · worked with me at Spryker
Recommendation excerpts written by colleagues on LinkedIn
"Guido is a thought leader in community building and developer relations. Any company serious about building an ecosystem should talk to him."
"Guido is an excellent public speaker who gives his audience practical tips on how to create a company culture that embraces evidence-based decision making."
"Guido consistently brought energy and openness, making it easy to connect on both professional topics and personal interests like AI and podcasting. He also excelled at connecting people across business and technology, turning community exchanges into actionable collaboration. Guido showed real leadership without ever being my manager, creating alignment and momentum simply by bringing people together."
"I'm amazed at how quickly he adopts new technologies. For example, he rapidly mastered cutting-edge topics like Agentic Development, Vibe Coding, and workflow automation. Bringing this to Spryker resulted in higher efficiency and quicker improvements, lowering our TCO."
