Rule-heavy products with many types of users.
01 · About
I design B2B products people enjoy using.
I work from the problem to the clickable prototype: research, design and validation, with a focus on design systems.
I use AI throughout the process and decide what goes into the product.

02 · How I use AI
I use AI to speed up the process. Design decisions stay mine.
Discover
MeI explore the real system before designing. I read the request, talk to the PO and look for the root of the problem.
AIHelps me organize what I found and test whether my reading makes sense.
Design
MeI map rules and flows and build the screens with the design system components.
AIDrafts the first versions. I choose what stays and refine.
Prototype
MeI build the clickable prototype in code, the way the product will behave.
AIWrites a good part of the code. I review the result.
Deliver
MeI validate with the PO and document for engineering: acceptance criteria, states and rules.
AIHelps write and check the documentation.
