Info

What I do

I build experience designs that balance business and user perspectives.

My background

I began in advertising design, then fell in love with product and service experience design. I’ve cut my teeth in startups and enterprises across entertainment, tech, web3, and e-commerce.

My approach

I believe good design starts with empathy. I ask questions, listen closely, and craft experiences that feel as honest and beautiful as they look—built to last. Always curious and open to innovation, I embrace emerging technologies like blockchain, Web3, and AI to accelerate ideation, streamline workflows, and push creative boundaries while staying grounded in user needs.
