After 20 years across product design and creative direction, I bring both. Agency work trained me to design for persuasion and brand impact.

The result is UX/UI work that looks considered, converts visitors, and gets built the way it was designed. ✅ 𝗖𝗢𝗥𝗘 𝗙𝗢𝗖𝗨𝗦 The clients I work best with are product teams and founders who need a UX/UI designer operating at both strategic and execution levels. I am equally comfortable running a UX audit, building a design system from scratch in Figma, or owning the full web design process from brief to handoff. My creative direction background means I think about brand, narrative, and conversion alongside usability. Industries: fintech and banking, SaaS and B2B platforms, e-commerce, healthcare, media, and enterprise software. ✅ 𝗠𝗬 𝗔𝗣𝗣𝗥𝗢𝗔𝗖𝗛 Every UX/UI design engagement starts with understanding the problem before opening Figma. I run a discovery phase covering user goals, business constraints, existing UX patterns, and competitive positioning. Wireframing and UX architecture come before any visual UI design decisions. This prevents the most expensive mistake in web design: building beautiful interfaces on top of broken user flows. I work in tight feedback cycles and deliver annotated Figma files with developer handoff specs, component documentation, and interaction notes so nothing gets lost between design and engineering. ✅ 𝗘𝗫𝗣𝗘𝗥𝗜𝗘𝗡𝗖𝗘 𝗕𝗬 𝗔𝗥𝗘𝗔 SaaS and Fintech Product Design: Core product experiences for fintech platforms, banking dashboards, and data-heavy SaaS products where UX/UI design must make complex information readable and actionable. Every engagement starts with UX research and flow mapping in Figma before UI design begins. Web Design and E-commerce: Brand-led marketing sites, conversion-optimized landing pages, and full e-commerce UI including product pages, checkout flows, and mobile web. CRO principles and A/B testing applied wherever performance data is available. Mobile App and Responsive UX/UI: Mobile-first UX/UI for iOS and Android with gesture-based interaction design, scalable component systems, and design consistency from mobile to desktop. Creative Direction and Brand: Brand identity, visual language, logo design, and strategic positioning work that connects product design to business narrative. 🚀 SKILLS - Web Design - Figma - User Interface Design - UX & UI - User Experience Design - Mobile App Design - Generative AI (Chat GPT, Clause, Genini..) 💡 Want a free UX/UI audit before we discuss scope?
