Baysal Sümer

I’m a Senior Product Designer with 8+ years of experience building design systems from the ground up and shipping accessible (WCAG 2.1 AA) interfaces for complex, multi-sided platforms. I focus on turning design-system rigor into real product velocity.

At Pickleball.com, I currently lead a three-tier, native-first design system that powers six web sub-products and two native apps for 75,000+ monthly active users. I reduced time to stand up a new native app from quarters to weeks and cut design-to-development handoff time by 40%, while owning the iOS native experience end to end alongside system work.

I’m hands-on with AI-assisted workflows, integrating Claude Code and research synthesis into my system practice to cut cycle time from spec to shipped components by ~30%. I collaborate component-based with front-end partners using my working knowledge of HTML, CSS, JavaScript, and React.

Previously, I designed UX/UI for US B2B companies at Newfangled, including Magnolia CMS contributions for Fortune 500 clients that improved content editor efficiency by 35% and reduced support tickets by 25%. As a Lecturer and UX Designer at the International University of Sarajevo, I led a zero-to-launch portal redesign with WCAG 2.1 AA accessibility and mentored 40+ students.
