I help companies turn designs into revenue.
I work at the intersection of design, engineering, and business. Not just aesthetics. I write the code, I work hands-on with AI tools, and I ship things myself.

That combination changes how I make decisions upstream. You stop designing for an idealized version of the product and start designing for what can actually be built, maintained, and grown.
My work has shipped to millions of users across education, SaaS, Web3, health tech, and consumer apps. I have taken brands from zero to millions of impressions, led design for products at the frontier of AI and consumer tech, and sat on founding teams whose products went on to define their categories.
Living in Tokyo sharpened everything. The city holds a standard for craft, service, and attention so high that mediocrity stands out immediately. I bring that lens to every product I touch.
I speak Spanish, English, Japanese, and Chinese, which means I can work with your team and your users wherever they are.

What I can do.
Most products ship the interface the team could build, not the one people actually needed. I start from how users move through your product and design the surface around that. Retention is the number that moves first.
I build and ship apps and websites end to end. Because I write the code, the handoff problem disappears. Nothing gets designed that cannot be built, and nothing gets built that quietly drops the design.
Brands rarely fail loudly. They drift, one off-brand slide and one improvised color at a time, until nobody recognizes them. Guidelines are what stop the drift, at any company size.
A logo is the smallest piece of your brand doing the largest amount of work. It gets one second to make an impression, then repeats that impression everywhere, for years.
Confusing buyer journeys usually get answered with more marketing spend. That is expensive and it treats the symptom. I fix the journey instead, so the same traffic converts and comes back.
Nine engagements, on record.
The magic of good design.
Sites with better experiences grow at nearly twice the rate. 88% of users never come back after one bad session, and you rarely hear why.
Usable design lifts conversion by up to 83%. On a typical 2 to 3% ecommerce baseline, good design adds another 66% on top.
AI driven personalization moves sales 15 to 20%. Targeted email drives transaction rates six times higher than the untargeted kind.
