Constantinos Demetriadis is a seasoned design and product leader with 13+ years of experience building scalable UI systems and consumer-facing digital products. As Design Operations & UI Lead for the LVMH Clienteling app he transformed UX visions into a reusable component library and a theme engine, and led a design system that cut handover time by 75% while enabling bespoke Maison theming. A serial founder and creative director, he runs Lovely Sim Racing and Lovely Productions and has a long track record launching UX publications, job platforms and startup products since 1998. He blends hands-on coding instincts (“my tool of choice is a hammer”) with deep product and visual design expertise, shipping tooling that converts design to production-ready code. His work spans agency-level creative leadership and engineering-adjacent tooling, delivering both award-winning campaigns and widely adopted side projects used by thousands of users. Based in Athens, he uniquely combines luxury retail product design experience with grassroots, community-driven product launches and sim-racing telemetry innovation.
