    AI-assisted digital experiences

I can take a project from the design file to the live page, the campaign email and the CMS.

AI speeds up the work. It doesn’t make the decisions.

I decide.

Product, design and technical decisions are mine: what to build, what to keep, what to cut.

AI builds and explores.

It accelerates ideation and implementation. On Vetegram, an AI coding agent wrote the code from my decisions.

I review everything.

Checking each milestone in the browser, I caught what the implementation missed. I removed an autoplay carousel, asked for a smoother hover and reworked an animation using animation principles. On Costa Ballena, I rejected a desktop layout built at 420px instead of 1440px, and icons that mixed styles.

Being open about this is part of what I offer.

Let’s build something.
