# Javier González · Baguelus > Product design · UX · DesignOps I’m Javier González. I design complex digital products and help product, design and development teams improve how they work with design systems and AI. - Portfolio: https://baguelus.com/en/ - LinkedIn: https://www.linkedin.com/in/javierbaguelus/ - ProductCrafter (Opening 1 January 2027): https://productcrafter.io/ ## I’m Javier González I’ve spent more than 25 years designing digital products. My favourite part is still finding out where people get stuck and building something that makes their work easier. Today, AI is part of how I do that, from early exploration through prototyping and delivery. Zurich–Munich corridor · Remote collaboration https://baguelus.com/en/sobre-mi/ ### Making complex work easier to navigate At Accenture I worked on an SAP-based employee tool. At the European Patent Office I contributed to digital patent registration, and at Allianz Technology I designed business applications for teams across countries. Talking to the people doing the work helped me decide what to simplify and what the process needed to keep. ### From discovery to delivery at Sunrise I led the redesign of My Sunrise, the portal where customers manage products, bills and contracts. I also led Sunrise Rewards from concept through the design of the portal and app. On both projects I combined research, workshops and prototype testing with a UI kit connected to the company’s design system. ### How I work with AI today I bring AI into the workflow from the start. I use agents to explore options, build prototypes and prepare handovers with rules the team can review. At Sunrise I implemented and tested a Figma-connected design system for front-end developers and agents, a plugin that checks component usage and prepares structured handovers, and a pilot that organises feedback for Product Owners. The app’s front-end team also tested the handover workflow. ### I like sharing what I learn I’ve mentored more than 100 UX students at CareerFoundry and coordinated master’s-level training at IED Madrid. I bring that experience to workshops and mentoring today. I’m also preparing ProductCrafter, a school and community where people can practise these ways of working together. ### What I bring today - **Product and UX** · Research, facilitation, product strategy, prototyping, validation and accessibility. - **DesignOps and design systems** · Tokens, component contracts and handover workflows connecting Figma, agents and front-end. I work with Figma MCP, GitHub, React and Storybook. - **Applied AI for product** · Agent workflows, automation, tool selection and output evaluation. My toolkit includes Claude Code, Codex, ChatGPT, Cursor, Lovable and n8n. I use Supabase and Hostinger when a prototype needs data or hosting. - **Training and adoption** · Workshops and mentoring that help design, product and development teams apply these practices to their own projects. ## Selected work https://baguelus.com/en/proyectos/ ### My Sunrise End-to-end redesign of the portal where customers manage products, bills, contracts and support. https://baguelus.com/en/proyectos/my-sunrise/ **The challenge** The portal brings together different tasks with their own business and technical requirements. The redesign had to make those tasks clearer within a shared experience. **My contribution** I led the end-to-end redesign. I organised customer interviews and stakeholder workshops and turned the findings into prototypes. I built a dedicated UI kit connected to the corporate design system. **Validation** I tested and iterated on the prototypes against customer needs, business requirements and technical constraints. ### Sunrise Rewards Designing the offers, tiers and points experience from concept to portal and app. https://baguelus.com/en/proyectos/sunrise-rewards/ **The challenge** Give members a way to understand and manage offers, tiers and points across three entry points. **My contribution** I led design from the initial concept, covering the dedicated portal, the My Sunrise integration and the app. I created a dedicated UI kit connected to the corporate design system. **Validation** I carried out internal and external research and validation with users and stakeholders as the experience took shape. ### A design system for AI Tokens, components and contracts connected to Figma and structured for front-end teams and AI agents. https://baguelus.com/en/proyectos/design-system-ia/ **The challenge** Explore how to share design decisions with the people building the interface and the agents taking part in the workflow. **My contribution** I implemented a decentralised design system connected to Figma and built a plugin to validate system usage and document handoff. The workflow generated React and Storybook packages and JSON for Storyblok. **Validation** The design system and plugin were tested within the Sunrise Design team. The handoff workflow was also tested with the app front-end team. ## How I can help https://baguelus.com/en/servicios/ ### Product design and UX Research, workshops, prototyping and validation for self-service portals, platforms and internal tools. https://baguelus.com/en/servicios/diseno-producto-ux/ **Where we start** We agree on the problem the product needs to solve and which decisions are still open. Interviews and workshops help us understand how people work and what constraints the team faces. **How we move forward** We turn findings into flows and prototypes that we can validate with users. We document decisions and identify what still needs checking before development. ### DesignOps and design systems Tokens, components and contracts that give design, front-end and AI agents a shared set of rules. https://baguelus.com/en/servicios/designops-sistemas-diseno/ **What we review** We follow a real workflow from Figma to code to find where information gets lost or work is repeated. We review tokens, components, documentation and how changes are checked. **What we can build** We prepare component contracts, documentation and handoff rules that designers, developers and AI agents can consult. We try the workflow on a real case from the team. ### AI adoption and training Task discovery, tool selection, pilots and workshops to integrate AI into design, product and development workflows. https://baguelus.com/en/servicios/adopcion-ia-formacion/ **How we choose a pilot** We start with a specific task and compare the current workflow with what AI might add. We agree which results the team should review and how we will decide whether to expand the pilot. **How the team learns** We combine prototypes, automation and practical workshops. The team learns to assess results and adapt the workflow using examples from its own work. ## Working notes https://baguelus.com/en/articulos/ ### What an agent needs from your design system A starting point for documenting components so that teams and agents can apply the same rules. https://baguelus.com/en/articulos/contratos-diseno/ **Start with one component** Choose one that appears across several screens. Document its purpose, supported variants, expected inputs and states. A button can specify when to use its primary style and how to signal that an action is in progress. **Connect the rule to implementation** Identify the equivalent component in code and link visual decisions to their tokens. Add a correct example and an edge case so the rule can be checked during review. **Test it on a small task** Ask the agent to use the component in a real flow and look for decisions that the contract leaves open. Use those findings to refine the documentation before extending it to more components. ### How to choose your team’s first AI pilot A way to pick a well-defined task and assess the result with the team that already does it. https://baguelus.com/en/articulos/primer-piloto-ia/ **Observe a repeated task** Choose a task with clear inputs and outputs, such as grouping customer comments for a product review. Agree on who will check the groups and which examples will serve as a reference. **Define the criteria before the test** Check whether the output preserves the meaning of each comment, whether the themes help people make decisions and how much correction is needed. Include ambiguous comments in the test. **Compare before deciding** Review the result alongside the existing workflow with the team. Record where it saves effort, where review is necessary and which errors would rule out using it. ## ProductCrafter 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. https://productcrafter.io/
