Senior UI/UX Designer with 5+ years of experience in Web3, crypto casinos, SaaS dashboards, and Figma design systems. I specialise in conversion-driven design that increases registrations and revenue.
I’ve led design for products in gambling, Web3, and SaaS — including bookmaker.xyz, Caswino, and a Web3 betting/casino (NDA). I built design systems from scratch, streamlined backoffices, and designed crypto social networks.
On my last Web3 project, I increased registration conversion by 500% and helped generate $100k+ in the first month after redesign. In Caswino, I built a backoffice and design system that reduced delivery time by 40%.
My main tool is Figma (components, auto-layout, prototypes, handoff). I design for clarity, scalability, and conversion — always making sure developers can implement easily.
Let’s work together if you need Web3, SaaS, or gambling interfaces that not only look premium but also drive results.

👉 Have an idea, existing product, or Figma file that needs a better design? Send me a message. I’m happy to take a look and share a few practical ideas before we even start.
I’m a UX/UI & Product Designer focused on mobile apps, SaaS platforms, web products and AI-powered experiences.
I care about more than making interfaces look good. I think about how the product works, what users need, what the business needs, and how to turn complex functionality into a simple experience.
🚀 What I can help you with
📱 Mobile Apps
• iOS & Android UI/UX
• New app design from scratch
• Existing app redesigns
• Onboarding & subscription flows
• Design systems & reusable components
💻 SaaS & Web Products
• SaaS dashboards
• CRM & business platforms
• Analytics interfaces
• Responsive web apps
• Landing pages & product websites
🤖 AI Products
• AI-powered mobile & web apps
• AI SaaS interfaces
• Chat & conversational experiences
• AI workflows and complex functionality
• Turning technical AI features into understandable UX
🔍 UX & Product Design
• UX audits
• User flows & information architecture
• Wireframes → high-fidelity UI
• Product improvements & redesigns
• Competitor research
• Prototypes for testing and development
🧩 My approach
I usually start by understanding what you’re building and why, rather than immediately opening Figma.
Then I work through the product flow, identify friction points, and create an interface that feels clear, intentional and visually strong.
My process can cover:
Idea → User Flow → Wireframes → UI Design → Prototype → Developer Handoff
And if you already have the UX figured out, that's completely fine too. I can focus purely on elevating the visual design and creating a polished, consistent UI.
🛠 Tools & workflow
Figma is my main design tool, with experience in:
• Design systems & components
• Auto Layout & responsive design
• Interactive prototypes
• Figma Make
• AI-assisted product development
• FlutterFlow & React Native workflows
Because I also experiment with building products using AI and no-code/low-code tools, I understand the connection between design and implementation, which helps me create designs that are not only beautiful but realistic to build.
✨ Products I've worked on
My experience covers AI, SaaS, FinTech, eCommerce, EdTech, Sports, Travel, Crypto/Web3 and productivity products, including both consumer-facing apps and complex business platforms.
I especially enjoy projects where there is something complicated behind the interface and the challenge is to make it feel simple.
Why work with me?
✔️ Product thinking, not just screen design
✔️ Strong visual attention to detail
✔️ Mobile-first and responsive design experience
✔️ Comfortable with complex SaaS & data-heavy interfaces
✔️ AI product experience
✔️ Clean, developer-friendly Figma files
✔️ Fast communication and collaborative workflow
✔️ Able to work from a rough idea, existing product, or detailed requirements
If you're looking for someone who can think about the product and design the interface, rather than simply move pixels around in Figma, feel free to send me your project.
Tell me what you're building. I'll tell you where I would start. 🚀
