Designer & builder
Curious about how products work —
and how AI changes the craft without replacing judgment.
Design systems humans use. Specs agents can parse. Same craft, two surfaces.
I’m a senior product designer with 8+ years shipping marketplace, SaaS, and design-system work — Homelike, ayoba, PortAventura, Reental, Bikiot, CaixaBank (fintech).
I write product decisions so they survive handoff — into Figma, Storybook, MCP, and markdown agents can read. 8+ years: marketplace, SaaS, systems, fintech (CaixaBank).
Lately I design with AI in the loop: Cursor, Claude Code, MCP. Side projects like Timeitt are how I pressure-test that.
Stack in the loop: Cursor · Claude Code · Figma MCP. Timeitt is the live sandbox. PortAventura MCP → Storybook is the production proof. Metrics still decide what ships.

PortAventuraWorld: Increasing Kiosk/App revenue + AI innovations
We increased kiosk and in-app revenue while shipping AI into the design-to-production loop: MCP from Figma design system to Storybook branch previews. Exact figures stay off the page (confidentiality). Engineering reviewed live components in PR context: fewer handoff gaps, faster builds.
Outcome: increased kiosk/app revenue (figures confidential). Pipeline: Figma DS → MCP → Storybook Design branch PRs. AI in the handoff path; metrics still decide what ships.

Sneakers
Sneakers are one of my longest-running design obsessions — silhouette, materials, colorways, the story behind a drop. Same eye I bring to product: details have to earn their place.
That’s why the pointer is an Air Jordan 1 Low OG x Travis Scott ‘Reverse Mocha’. Not a random cursor. A quiet signature for anyone who looks twice — and a reminder that craft lives outside Figma too.
Personal system note: sneakers = long-running craft obsession (silhouette · material · colorway · drop narrative). Same taste filter as product work.
cursor: air-jordan-1-low-og-x-travis-scott-reverse-mocha — intentional signature, not decoration. Notice the toes; that’s the hotspot.
About
Family, friends, sports, and freedom — that’s what I fight for.
One of my deepest passions is traveling — solo, and with friends and family. Right now I'm making my way through The Lord of the Rings trilogy and Dostoevsky.
Design is attention. AI is leverage. Markdown, tokens, and MCP are how judgment travels into systems without getting lost in a slide deck.
This toggle isn’t a gimmick — it’s the job: product for humans, specs for the agents and engineers who ship with you.
