💎 Top 1% Expert-Vetted
🏆 Top Rated Plus
✅ 250+ projects delivered across fintech, SaaS, e-commerce, and enterprise products.
20 years of UX/UI design experience, including a decade as creative director at global agencies like Iris Worldwide London, HAVAS Paris, and Young and Rubicam New York. I design products that are not just visually sharp but strategically built to convert, retain, and scale.
Ready to discuss your project? 𝘀𝗲𝗻𝗱 𝗺𝗲 𝗮 𝗺𝗲𝘀𝘀𝗮𝗴𝗲 or schedule a quick call directly from my profile. I respond immediately.
Below are my services:
✅ 𝗪𝗛𝗔𝗧 𝗜 𝗗𝗢
I cover the full UX/UI design lifecycle, from initial research and wireframing through to high-fidelity Figma prototypes and production-ready design systems.
My web design work spans SaaS platforms, fintech dashboards, e-commerce, and mobile applications. Whether a client needs a complete product design overhaul or a focused UX audit, I bring the same structured, research-backed approach every time.
Core UX/UI design services: product design strategy and UX architecture, complex wireframing and information hierarchy, rapid prototyping and interactive Figma components, design systems and UI libraries, user research and usability testing, heuristic analysis and CRO-focused UX audits, and creative direction including brand identity and visual language.
Tools: Figma, Webflow, Sketch, Adobe XD, Illustrator, Photoshop, InVision, Axure, Hotjar, Mixpanel, Fullstory, Google Analytics, and UserTesting, Generative AI, Chat GPT, Nano banana, Claude, Gemini.
✅ 𝗞𝗘𝗬 𝗔𝗖𝗛𝗜𝗘𝗩𝗘𝗠𝗘𝗡𝗧𝗦
- 250+ UX/UI design projects completed with a consistent 5-star track record across the US, Europe, and Asia.
- Recent highlights: a fintech core banking platform for Omniwire, simplifying complex issuer workflows into an intuitive product design across multiple markets.
- A personal finance web application for MoolaX where the UX design reduced onboarding drop-off by restructuring information hierarchy and simplifying the dashboard UI.
- A full product design and web design build for Austrian Audio, turning a high-end audio brand into a conversion-optimized e-commerce experience across desktop and mobile.
✅ 𝗪𝗛𝗔𝗧 𝗦𝗘𝗧𝗦 𝗠𝗬 𝗨𝗫/𝗨𝗜 𝗔𝗣𝗔𝗥𝗧
Most UX/UI designers are strong on research or strong on visuals. After 20 years across product design and creative direction, I bring both. Agency work trained me to design for persuasion and brand impact. Product design across 250+ projects taught me to design for clarity, retention, and real user behavior. 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..)

👋 Hi, I’m a 🚀 🚀 🚀 🥇Top Rated Plus Full-Stack Developer 🚀 🚀 🚀 with over 17 years of hands-on experience building powerful, user-friendly web and mobile applications — from idea to launch and beyond.
I’ve successfully completed 🔥 20+ long-term projects 🔥🔥🔥 on Upwork, partnering with clients from around the world to deliver solutions that are not only technically sound but aligned with real business goals.
Whether you’re a startup looking for an MVP, or an established company needing to scale and refactor a legacy system — I’m here to help make it happen, smoothly and efficiently.
Here’s what it’s like working with me:
🧩 I figure things out. Fast. From legacy spaghetti code to shiny new stacks — I dive in, untangle, optimize, and deliver.
📢 I communicate like a human. You’ll never get vague tech talk from me. I keep you in the loop, explain the "why" behind choices, and always deliver with clarity.
🛠️ Full-stack is my comfort zone. Whether I’m building snappy UIs or crafting efficient backends, I move comfortably across the stack — and make it all work together like a dream.
💡 I care about what we’re building. Your goals are my goals. I’ll offer ideas, challenge assumptions, and help make smarter decisions (not just code what’s asked).
🤹 I’m independent but team-friendly. I play well with others, but I’m also happy to take full ownership when needed and just get things done.
🔄 Always learning, never stuck. New tools, new frameworks, weird edge cases — bring it on.
Long story short: I love building things that are useful, clean, scalable, and even a little fun. If you're looking for a dev who’s reliable, thoughtful, and maybe even a little witty — let’s connect!
