Atienza

I lead product at enterprise scale: Tesla's global eCommerce across 40+ markets, the buyer-facing surface of Siemens' €79B business, and DEMMANND, which I designed and built end to end.

About

I build the layer where buyers decide.

Currently · Siemens

I am a first-principles product and technology leader with an unusual combination of commercial scale, enterprise product leadership, and hands-on technical depth. I owned Tesla Shop as it grew into a global ecommerce business generating more than $200 million annually across 40+ markets. I now lead product strategy across Siemens' global digital experience. In parallel, I independently conceived, architected, designed, and engineered a production multi-tenant AI platform from first principles.

I am insatiably curious, highly analytical, and hands-on. I flow comfortably from customer and business problems into product strategy, system architecture, engineering, launch, and measurement. I have built products from zero, operated them at global scale, and led complex enterprise transformation.
