About me
Hey!
I'm Kate.
Senior UX/UI Designer · Product Designer · Web & Mobile · SaaS · Design Systems
Based in Lille, France
I turn complex product challenges into clear, thoughtful experiences that feel natural to use.
For more than a decade, I've designed digital products across fintech, crypto, AI, SaaS, healthcare and global enterprise platforms. I care about the person on the other side of the screen — and about connecting their needs with strong product and business thinking.
Design is more than my work; it's genuinely one of my favourite hobbies. Away from the screen, I'm happiest staying active — running, doing sports, travelling and discovering new places. That curiosity and energy always find their way back into how I collaborate and create.
Always happy to connect.

How I can be helpful
From idea to impactHow I can help your product.
I join teams where clarity, momentum and thoughtful product craft matter.
For new products 🚀
I can lead your concept from strategy to implementation — covering the full product cycle from ideas and hypotheses to development support. I conduct qualitative and quantitative research, generate and test hypotheses, create user flows, wireframes and visual designs for web and mobile, and validate them through usability testing.
For product redesigns ✨
If you have existing software that could work better, I help transform it from friction to flow. I audit the experience, identify usability issues, improve information architecture and interaction patterns, modernise the visual system and deliver scalable, development-ready solutions.
