Haşim Emre Özöcal

London-based Senior Product Designer. I design products, apps and websites. I build and launch them myself.

I've designed for American Express, Net-A-Porter, Mr Porter, Sage, Decathlon, Euro Car Parts, Chelsea FC, Hobbycraft, Mumsnet and Artfinder, and made Nouva, an AI stylist with 1,000+ downloads.

Case studies

The problem, the decisions I made and what changed.

Nouva — An AI stylist, designed and built solo

Nouva suggests outfits from your own wardrobe for the weather. I designed, built and launched it on my own, and it has passed 1,000 downloads.

E-commerce & conversion

Sole designerResearch & redesignA/B tested in the UK

Sage — A product page that asks who you are

People struggled to tell which plan suited them. In the first three weeks of a UK A/B test, my redesign’s conversion rate was 19% higher, though the test hadn’t yet reached statistical significance.

Tokens & componentsLed 4 designers

Net-A-Porter & Mr Porter — One design system for two luxury brands

I built the token architecture and every component for both brands, then led a team of four designers.

E-commerce & conversion
