The Short Version

I'm Stylianos — a Senior Product Designer with 15+ years turning complex, messy problems into products that millions of people actually want to use.

I've built design systems that scaled across 15+ teams, shipped AI-driven personalization that tripled conversion, and led design functions that moved the needle on engagement, satisfaction, and retention. My work spans Compare the Market, Currys, and iD Mobile — three of the UK's most demanding digital platforms — where research, data, and craft were never optional.

I care deeply about the work. I'm as comfortable in a strategy session with stakeholders as I am obsessing over spacing in Figma. I hold a high bar — for myself and the teams I work with — and I believe the best design solutions are always the ones that make something genuinely hard feel effortless.
