Industrial designer who builds software.
I'm Alp Yenigün. For years I designed products, packaging and the interfaces other people built — always closest to how things get used, never to the code. In 2026 AI coding tools closed that gap, and now I design, build and run complete products myself.
My main product, Neuday, runs the daily operation of a cosmetics manufacturer with several brands, so what I make gets used for real the next morning.
Neuday
An operations workspace: customer service across every channel, Kanban with work forms and approvals, team chat, stock, orders and shipping. Built for a multi-brand cosmetics manufacturer — its first customer — whose staff use it every day.

Ski maps that look hand-drawn, with real terrain underneath — 4,116 resorts on the web, and a native iOS tracker for the coming season.
