Product Designer & UX Designer · Berlin

I design products end to end — from user research to shipped code.

I'm Keivan Sina, a senior Product and UX Designer with 10+ years of experience across Berlin, Kuala Lumpur, and Tehran. I take products from user research and Figma all the way to production React, so what gets designed is what gets shipped.

My focus is design systems, complex enterprise UX, and AI-powered features. At Instapro I scaled a design system across five brands, raised adoption by 25–40%, and built a Figma plugin that generated 1,500+ icon components. At PETRONAS I led UX research and design for an operations platform with 100+ screens. At IRSA I launched the SafarMarket travel marketplace from zero on web, Android, and iOS.

Today I work as a Design Engineer at Jakota Design Group in Berlin, shipping AI features and WCAG accessibility improvements for client products. MS in Artificial Intelligence · German C1 · English fluent.
