About Karine

Product Designer, I work on complex, engaging or constrained products, where users hesitate, make mistakes or give up.


I primarily focus on high-stakes journeys: onboarding, engaging decisions, regulatory products, business platforms, administrative procedures.

My role is to help users understand, decide, and move forward, by transforming business and technical constraints into fluid experiences.

I collaborate closely with product, tech, and business teams, with a high degree of autonomy in framing, trade-offs, and design choices.

My work begins where users hesitate, doubt, or abandon.
