I've held product design — or similar — roles for 20-odd years now. The job titles change but the skillset remains the same: research, prototyping, interface design and design leadership.
I've taken companies from zero to one on three occasions so far, and many more projects from an idea to something tangible.
My work has often been in a technical setting: geospatial analytics, data science, natural language processing. And mostly in b2b SaaS, with fields from video production to counter terrorism and SEO to security.
