Crafting products people actually want to use.

Tomás Milgron

Product Design Engineer

I started in editorial design and ended up building digital products. Nine years of closing the gap between design and engineering, owning both sides of the work instead of handing off between them. I design systems and build them: Figma token architecture to production-ready Vue and React interfaces. Increasingly, my work focuses on building products based on human-AI collaboration.

Selected Work

Two products of my own built from scratch, three years inside an insurtech and a workshop method. Each card says what the problem was, who did what and how it turned out. Open one for the whole project.

Anansi

From a four-page PDF to a Design System.

First design and frontend hire at an insurtech that insures deliveries and resolves claims. The design system, the design and front of its products, three apps brought into a single architecture, and claims intake from 14 steps to 5 clicks.

Carta

The business card that people, phones and agents can read.

An address under your domain that, tapped or scanned, shows who you are, saves your contact to the phone and tells an agent how to talk to yours. NFC, QR, Wallet. And agents. Stationery, extended.

Tend

The health record that follows adopted animals.

A health record the rescue group starts and hands to the adopter on adoption day, as a link over WhatsApp. The adopter inherits the history and the vet treats with full context. From the first interviews to the MVP.

COLAB Sessions

Deciding what to delegate to AI and what to keep as human gesture.

A four-step framework (problem, actors, context, hypothesis) to go from idea to working prototype in one afternoon. Two intensive sessions and the master's at IED Barcelona, with 35+ students.

Lab · 02 experiments

Experiments, with no client and no rush.

Pieces made out of curiosity: an idea pushed until it breaks. They answer no brief; what they teach ends up in the ones that do.

Sintonía: a question mark in ASCII and a row of dimmers

Sintonía

Typographic dimmers modulated by a language model.

Built as an instrument: a set of typographic dimmers you turn by hand, with a language model turning them alongside you. Motion, type and model in the same loop.

Motion

Interfaces that move with intent.

Motion as a capability, not decoration: one shared vocabulary of easing and duration, physics over choreography, reduced motion as a first-class variant and accessibility that survives the trick. The studies are live: touch them.

About

Product Design Engineer with 9 years closing the gap between design and production code. I design systems and build them: Figma token architecture to production-ready Vue and React interfaces, with the Backend For Frontend layer that most teams leave as an afterthought. I lead the user research that defines what gets built.

At Anansi I joined as first design and frontend hire, when the brand was a four-page PDF and the product two disconnected apps. I left a design system the whole team uses, and, with the Product Manager and the backend team, a single Next.js architecture with a BFF layer. At IED Barcelona I teach AI-augmented design workflows. At Taller Oliva, my own studio, I build products end to end, from the Postgres schema to the last easing curve. Carta, a business card for people and agents, is in production.

The best products come from people who can see the whole picture: from the token in Figma to the API contract in the backend, and increasingly, from what the system does autonomously to what the human still has to decide. That's what design engineering means to me now.
