Profile

Seven years ago I started designing interfaces for complex systems — blockchain protocols, DeFi platforms, healthcare apps and Web3 marketplaces. The common thread: making technically dense products feel simple, trustworthy and worth using.

I work across the full design arc: discovery and user research, information architecture, interaction design, high-fidelity UI and design systems built for engineering handoff. I know Figma deeply, think in components and have shipped 20+ products to production.

Today I also bring foundational HTML, CSS and JavaScript into the workflow — enough to prototype in code, read pull requests and close the gap between design intent and what actually gets built. I work daily with Claude, OpenAI Codex and n8n to automate and accelerate every phase of the process.
