Eight worlds
of experience.
One living core.
I'm Daniel Grzeszczak. Product designer, strategist, researcher and product owner in one. Everything a product needs to work. Eight industries shaped me over 15+ years. I am the 9th pipe: the one that connects them into one product.

Not separate chapters.
A connected whole.
The value isn't in knowing one world. It's in connecting what different worlds can teach us.
Experience overlaps across industries. The years are not a sum; they are different ways of seeing the same complexity.
Every product is a home renovation.
As many residents, as many opinions. Someone has to hold the plan.
Discovery before delivery.
The problem, the North Star metric and the information architecture are set before a single screen ships. Polishing a broken flow only adds expensive debt.
Stakeholders aligned, not appeased.
Users, business, legal and engineering pull in different directions. I make the trade-offs explicit and turn them into one prioritised roadmap.
Prototype, validate, then commit.
AI-native prototyping lets me test options with real users in days, not sprints, before engineering writes a line of code.
