About

I’m Martin, a product design leader with a multidisciplinary background in human-centered design and digital transformation. I create intuitive, accessible digital products that align with business goals and drive measurable growth.

I’ve collaborated with brands like Carvana, Progress Residential, InEight, and INC, building top-notch experiences and delivering tangible outcomes. I’ve also built AI-powered platforms (UXTail and RocketGeoAI) to streamline UX research and boost e-commerce visibility.

Recently I led discovery, user research, and an AI-enabled MVP for Vail Resorts’ EpicPass, improving purchase flows and reducing friction to boost conversion.

I love collaborating across product, engineering, and research to close experience gaps and craft scalable design systems that empower teams while ensuring accessibility and inclusivity.
