SETH MCCAY
Summary
Product designer with 10+ years spanning consumer apps, B2B tools, and entertainment industry campaign design. I design commerce flows, dashboards, and data-heavy interfaces that ship to real users — then iterate based on what breaks. Currently a Senior Designer at HarperCollins Publishers; I also work as sole designer for Distinguished Concerts International New York, branding 100+ concerts at Carnegie Hall and Lincoln Center. I have been working inside the music industry, not just around it, since 2018.
