Design for
complexity.
I’m Javier González. I’ve spent more than 25 years designing self-service portals and internal tools, and today I build design systems that both teams and their AI agents can use.
I help product, design and development teams understand complex problems, make better decisions and bring AI into everyday work through pilots, workshops and mentoring.

Product design and UX case studies, from customer self-service to design systems prepared for AI.
Complete redesign of My Sunrise
A self-service platform built from scratch for Sunrise customers. Two years in real use and almost no usability problems.
- 50 users in the tests
- 3 iteration cycles
- 2 years in real use
Sunrise Rewards
A loyalty programme built from scratch, with no requirements, across portal, My Sunrise and app. From sketch to a 1,500-employee pilot in 6 months.
- 6 months from zero to pilot
- 1,500 employees in the pilot
- 3 platforms
A design system for AI
An open design system architecture, in a repository, that design, front-end and AI agents consume the same way. Tested in a pilot with the app team.
- 4–5 months of work
- 1 author, with AI
- 4 people in the pilot
How I can help
I help product, design and development teams with UX, design systems and AI adoption.
Product design and UX
Research, workshops, prototyping and validation for self-service portals, platforms and internal tools.
DesignOps and design systems
Tokens, components and contracts that give design, front-end and AI agents a shared set of rules.
AI adoption and training
Task discovery, tool selection, pilots and workshops to integrate AI into design, product and development workflows.

I like starting digital projects and trying ideas that rarely fit into client work. Sometimes I end up with a product, sometimes with a better question.
ProductCrafter is a school and community for people who build products with AI. I’m preparing video courses, live workshops and mentoring, with a space to share projects and learn from each other.
