George Yiakoumi

Senior Product Designer, London

Creative, user-obsessed UX/UI Designer with 10 years of experience designing digital products that make sense to real people. I bring together clean UI, motion finesse, and strategic UX thinking to ship experiences that are functional, scalable, and sometimes even fun. Experience gained across transformation, innovation, and the finance, healthcare, tech and retail sectors.

I thrive in collaborative environments, obsess over accessibility, and have a soft spot for design systems, Web3 experiments, and sketchbooks full of ideas. Always learning, always building.
