7+ years designing complex Web3 products — trading platforms, dashboards, dApps and data-heavy interfaces. Strong in simplifying complicated systems without sacrificing depth or visual quality. My experience spans Prop Firms, DeFi, dApps, wallets and trading platforms. I work across UX, UI and product thinking — shaping flows and product structure, building scalable design systems, and taking products through to polished final interfaces.
