A Web3-focused designer who built the user experience of a multi-billion-dollar unicorn product from scratch. I believe in cross-disciplinary design thinking to drive innovation and creation. I excel at decoding complex products and crafting joyful user experiences. Thriving on challenges across any medium or domain, I look to collaborate with visionaries to bring their dreams to life.
