About Marianne
I’m a Product Designer focused on creating clear, intuitive digital products for complex systems and user flows.
I’ve worked across sustainability, citizen science, mobility and health projects, designing dashboards, mobile apps and web platforms that help users better understand information, complete actions and navigate complex experiences.
Most of my experience has been in fast-moving or low UX maturity environments, where I’ve collaborated closely with teams to bring structure, clarity and consistency to products while balancing user needs, business goals and technical constraints.
I’m increasingly integrating AI-assisted tools and workflows into my design process to support ideation, accelerate iteration and explore solutions more efficiently.
Strengths
• UX/UI for SaaS platforms, dashboards and digital products
• Complex user flows & information architecture
• Scalable and systemized UI design
• Designing with data and technical constraints
• Product thinking & cross-functional collaboration
I enjoy working with teams that care about thoughtful design, clarity and meaningful user impact.
