What I'm looking for

I'm seeking senior product design roles where I can lead design systems, drive mobile-first UX, mentor teams, and deliver measurable improvements in retention and conversion within a collaborative, data-informed company.

I am a creative digital product designer with over 10 years’ experience shaping brand identities and solving complex UX/UI problems for both multinational and SME organisations. I combine simplicity with user empathy and defend design decisions with data, research, and trends.

I specialise in building and refining design systems, pattern libraries and UI Kits in Figma and Sketch, turning large-scale products into intuitive services. I have led multi-brand GDS implementations and mobile-first design initiatives that simplified experiences and boosted retention and conversion.

My day-to-day work spans the full UX/UI lifecycle: research, personas, wireframes, user flows, prototyping, user testing and developer handover. I champion accessibility, motion-led interactions, and pixel-perfect visual design while collaborating closely with product and engineering teams.

I'm comfortable leading design teams and sprints in fast-paced environments and bring an entrepreneurial, analytical mindset to every project. I seek to deliver measurable outcomes, mentor others, and create cohesive products that delight users and meet business goals.
