About Kate

Bilingual French-American, I support companies and users in creating value through digital B2B and B2C products and services, covering the entire product lifecycle.

Specialized in requirements framing, user research, and the design of scalable solutions, I work end-to-end—from strategy to execution, from VQA to KPI monitoring—to build unified experiences that are consistent with brand identity and directly aligned with business OKRs.

I navigate complex environments with ease (equity derivatives, renewable energy, film rights/licensing...), where I facilitate cross-functional initiatives and lead the resolution of systemic problems. I rely in particular on customer experience mapping to identify levers for journey optimization, while ensuring smooth collaboration between product, tech, business, and design teams.

For me, design goes beyond craft — it’s a way to uncover opportunities, align teams, and create experiences that deliver real business and user value.
