in the Czech Republic

I am UI UX Designer with 10 years of experience. UI UX Design is my main skill. ✔ 𝐒𝐭𝐫𝐚𝐭𝐞𝐠𝐢𝐜 𝐃𝐞𝐬𝐢𝐠𝐧 𝐓𝐡𝐚𝐭 𝐌𝐨𝐯𝐞𝐬 𝐘𝐨𝐮𝐫 𝐁𝐮𝐬𝐢𝐧𝐞𝐬𝐬 𝐅𝐨𝐫𝐰𝐚𝐫𝐝 Most clients come with the same problem: their product looks fine, but doesn't convert. Users drop off, flows feel confusing, the interface gets in the way As a Senior UI UX Designer, SaaS Designer, Figma Designer, and product designer with 8 years of experience, I close the gap between how your website or mobile app looks and how well it works. My work covers B2B saas platforms, saas dashboards, enterprise software, mobile app design (iOS and Android), AI products, ecommerce, and marketplaces Everything is built in Figma – from wireframes and clickable prototypes to production-ready, responsive assets. Whether you need a modern website redesign, a clean mobile-first landing page, an MVP, or a mobile app design from scratch, I bring the same research, structure, and craft. That's what working with a senior UI UX Designer should feel like ✔ 𝐖𝐡𝐚𝐭 𝐖𝐨𝐫𝐤𝐢𝐧𝐠 𝐖𝐢𝐭𝐡 𝐌𝐞 𝐀𝐜𝐭𝐮𝐚𝐥𝐥𝐲 𝐋𝐨𝐨𝐤𝐬 𝐋𝐢𝐤𝐞 As a UI UX Designer focused on B2B saas, every engagement starts with users and business goals, not jumping into screens. UX & UI work in parallel from day one. From there: – UX Research, design audit, and user journey mapping – User Experience Design that maps friction in user flows – Information Architecture and Wireframing for complex saas platform logic – User Interface Design and Mobile UI Design in Figma with disciplined typography, spacing, and visual hierarchy, as scalable design systems – UI/UX Prototyping and clickable Prototyping for user flows and onboarding flows before dev handoff – Usability Testing and accessibility-conscious design (WCAG-aware) for user-friendly modern products – Design handoff with Figma components, design system tokens, and brand guidelines I work across web design and mobile app design equally. Your B2B saas Figma design system delivers scalable, component-based interfaces. Your ecommerce website design feels intuitive end-to-end. Your booking or marketplace product stays consistent across iOS, Android, and web app. Your landing page is built around conversion logic, not visual design polish ✔ 𝐖𝐡𝐚𝐭 𝐅𝐚𝐥𝐥𝐬 𝐎𝐮𝐭𝐬𝐢𝐝𝐞 𝐌𝐲 𝐒𝐜𝐨𝐩𝐞 – I'm a UI UX Designer, not a web developer: no website development, WordPress development, or front-end implementation – Not a mobile or game developer, and I don't build in Webflow, Wix, Shopify, or React Native, but my Figma files are ready for any of them – I don't write React code or take on marketing tasks Happy to collaborate with your dev team on handoff and QA ✔ 𝐈𝐧𝐝𝐮𝐬𝐭𝐫𝐢𝐞𝐬 𝐚𝐧𝐝 𝐑𝐞𝐬𝐮𝐥𝐭𝐬 I've worked across B2B saas, enterprise software, fintech, healthcare, ecommerce, food delivery, booking and marketplace platforms, AI products, and gaming – 60% more user engagement and 45% faster task completion, after a website redesign for a B2B saas analytics platform – 40% boost in sales and 50% drop in bounce rate, following a landing page and mobile app design refresh for an ecommerce website – 70% faster onboarding and 80% higher satisfaction, after redesigning a healthcare mobile app as a long term collaboration – 65% better user retention, driven by high-fidelity designs across a fintech saas dashboard and its companion app That's what happens when a UI UX Designer treats product design as a discipline, not decoration ✔ 𝐁𝐞𝐲𝐨𝐧𝐝 𝐔𝐈 𝐔𝐗: 𝐅𝐮𝐥𝐥 𝐕𝐢𝐬𝐮𝐚𝐥 𝐈𝐝𝐞𝐧𝐭𝐢𝐭𝐲 𝐒𝐮𝐩𝐩𝐨𝐫𝐭 When the project calls for it, I also step in as graphic designer, web designer, and brand partner. Graphic Design covers Branding, Brand Identity Design, brand guidelines, logo design, style guides, icon sets, and print materials, all consistent with the website design and product. Visual identity stays cohesive across website and mobile app ✔ 𝐓𝐨𝐨𝐥𝐬 𝐈 𝐖𝐨𝐫𝐤 𝐖𝐢𝐭𝐡 As a Figma Designer building saas figma systems, Figma and FigJam sit at the center of my workflow, from Wireframing and clickable Prototyping to polished ui design and dev handoff with Figma components. Also Sketch and Adobe XD when needed. For production and motion: Adobe Photoshop, Adobe Illustrator, InDesign, Adobe After Effects. Prototypes validated in InVision ✔ 𝐖𝐡𝐲 𝐂𝐥𝐢𝐞𝐧𝐭𝐬 𝐊𝐞𝐞𝐩 𝐂𝐨𝐦𝐢𝐧𝐠 𝐁𝐚𝐜𝐤 As a Ui ux Designer and Figma Designer with 200+ projects, clients come for the visual quality and stay because the work actually solves problems. You get a Senior UI UX Designer for Web Design, mobile apps, and B2B saas, who asks hard questions early, communicates clearly, and delivers files your team can actually use Available for both short briefs and long term partnerships.
