- Discovery, prototyping & user testing
- Data-driven optimization (A/B tests, analytics, conversion)
My strength: transforming complex challenges into simple, elegant, and impactful experiences, through an approach combining artistic creativity, product strategy, and data rigor.
I support your teams to accelerate and structure: workshops, scoping, design, design/product coaching, art direction, and delivery.
