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.

N°01 — ABOUT
An Apple Design Award winner with an MBA and a background in software engineering
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.

THE TOOL I BUILD WITH EVERY DAY. NOTHING I SAY ABOUT SHIPPING WITH AI IS THEORETICAL.
N°02 — MY OWN APPS
Apps owned by me
Client work is most of what I do, and most of it is under someone else's name. These three are mine end to end: my idea, my design, my code, my name on the App Store listing.
N°03 — CAPABILITIES
What I can do
Product Design
Most products ship the interface the team could build, not the one people actually needed. I start from how someone moves through your product, then design the surface around that. Research, flows, prototypes, the screens you actually ship. Retention is the number that moves first.
Software Development
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.
Content Marketing
A brand nobody sees is just a style guide. So I do both halves: the branding and visual design that make you recognizable, and the articles, pages and video that put you in front of people. One hand on both, which is why they never drift apart.
Monetization
Plenty of products are loved and still do not make money. Pricing, packaging, the paywall and the moment you ask for the upgrade are design problems long before they are spreadsheet problems. I have shipped these on real subscription products and watched the revenue move.
Conversion & Growth
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.
