Hello allegro.

I'm End-to-end Product Designer shaping complex systems with a service mindset.

I help organizations untangle complexity - turning messy processes, fragmented services, and unclear user journeys into coherent, purposeful product experiences. Currently exploring AI-augmented design workflows.

8+ years designing at scale.

With my experience across telecom, healthcare, finance, and e-commerce, I've learned that the best design decisions come from deep understanding - of the business, the organization, and the people involved.

I work best in the messy middle: where stakeholder interests collide, where legacy systems constrain, and where clear thinking is most needed.

"I had the pleasure of having Kate in my team, where she consistently brought a calm, thoughtful approach to her work.

She was a great presence in the team, and I'm sure she'll be the same wherever she goes next."

Ashton Snook

"Kate is a true professional. Her broad range of product design skills, combined with her calm, collaborative, and teachable attitude, make her someone you can trust to handle even the most challenging tasks. (…)

I thoroughly enjoyed collaborating with her, she made my job easier, and together with the product team, we designed some great features for Vodafone customers."
