Product Designer · Design EngineerSantiago, Chile · Remote

I design and build digital products end to end.

AI can be part of the experience, part of how the product is built, or both.

For 15+ years, I've worked across product direction, research, interaction design, systems and production code.

I built a Design System and a framework that help teams and coding agents carry product intent from specification to production across internal products.

AI in the product · Samsung

I researched, designed and helped build Teiky, an AI voice and chat assistant for retail sellers: the experience, React Native app and part of the backend.

Keeping people and coding agents on the same page

I built a Design System, then turned its product rules into shared infrastructure for people and coding agents—helping teams carry product intent into production across different internal products.

Problem

Coding agents could generate interfaces quickly, but product decisions were getting lost between intent and implementation.

What I changed

I created the Design System from zero, then treated its documentation, the product specs and the implementation rules as one shared infrastructure.

In production

The Design System is used across multiple internal products in the GenAI and Data area; the framework is used in several of those projects.

Product knowledge, as a conversation

Samsung retail sellers needed product information while they were already talking to customers. I researched, designed and helped build an AI assistant they could use through voice, text or a familiar content library.

Shipped

The React Native app with voice chat and a local content library, on Azure, with OTA updates. Used by Samsung's sales team and by external sellers across Chile.

Constraint

A salesperson is talking to a customer, comparing devices and looking for information at the same time.

Decision

Away from deep navigation, toward faster, conversational access to knowledge. Voice as one way in, not the only one.

From lockdown to 240K users

I started ComediaPlay when live entertainment stopped during the pandemic. I designed, built and operated almost the entire product myself until closing it in August 2026; most activity was concentrated through 2024.

Users: ~240K
Paid digital accesses: ~400K
Transaction volume: ~US$3.5M
Peak concurrent users: ~10K

Ownership

Product, design, development, infrastructure and operations. Accounting was basically the only part I didn't own.

Architecture

WordPress kept where it was useful; database isolation, load-balanced nodes, shared Redis, Rust WebSocket services for realtime.

Generative AI · 2023–24

Creator insights from deterministic metrics, and AI-assisted event descriptions. The system stayed the source of truth.

Capabilities

I tend to follow the problem across layers instead of stopping at the interface.

How I got here

My career has always crossed product design and engineering.

The titles changed: UI Developer, UX Designer, Product Designer, AI Product Engineer. The habit didn't. I follow the product problem as far as it needs to go, and sometimes that means research and interaction design, sometimes a specification, a prototype, an API change or the infrastructure getting in the product's way.

Today that gives me two complementary ways to use AI: designing products where it belongs in the experience, and using AI-native workflows to build products of any kind.
