UX/UI Designer · Warsaw · 8+ years

Several words about myself

I'm a Senior UX/UI/Product Designer with 8+ years of experience. I lead end-to-end product work: from research, data analysis, hypothesis framing, and user journey mapping to interactive prototypes, usability testing, and developer handoff. I build and evolve design systems (Figma, design tokens, a component-driven approach based on Ant Design/MUI/Material) to speed up releases and improve consistency.

I've led designers, setting quality standards, running reviews, mentoring, and streamlining processes. My experience spans web platforms, B2B dashboards, SaaS products, and marketing pages, as well as branding and guideline development. I base decisions on funnel data, behavioral analytics, and user interviews to ensure measurable impact on key metrics. I'm ready to strengthen the team as a hands-on senior: simplifying and accelerating critical user flows and scaling the design system for growth.
