"A designer who dove into code"
In 2003, I started as a graphic designer: posters, albums, and branding. Gradually, I moved closer to code, stepped into UX/UI territory, swam through HTML/CSS waves, dove into JavaScript, descended to feel the pressure of PHP, and in the depths, I discovered a new creature: AI.
The journey transforms me—I become a fish-man. A designer who codes their designs, a programmer who designs their own interfaces, both now amplified through AI. Someone who can help you:
- Create tools that integrate AI into design and development workflows: MCP servers and multi-agent systems.
- Design architectures and procedures for teams looking to integrate AI into their processes, documenting them through technical guides.
- Develop interfaces that materialize the vision of UX/UI teams through clean, maintainable code.
- Act as a bridge between design and development teams, optimizing and standardizing processes.
I currently work at Making Science, working remotely based in Vitoria-Gasteiz, collaborating with clients such as Universidad Europea, Metrovacesa, Rafa Nadal Academy, and Pibank, while driving AI integration into the company's development processes.

- Developed the corporate base theme and generated technical documentation to standardize all team projects.
- Supervised the development of projects such as Rafa Nadal Academy, BNB, and You First.
AI
2023
- I started using ChatGPT to write code. First in a rudimentary way, then introducing prompt engineering.
2024
- I adopted GitHub Copilot as my main coding assistant, exploring its advanced features to optimize my workflow.
- I experimented with different LLMs and advanced prompt engineering techniques.
2025
- I adopted Cursor as my main development tool.
- I participated in an internal initiative to promote AI integration across all departments, developing technical guides on MCPs, context/memory extension, and Figma integration with agents.
- I joined a research and development group to create multi-agent tools that automate the software development cycle.
Personal projects
- I developed with my colleague Olivier a multi-agent system (CrewAI) to automate code documentation, refactoring, and testing. We suspended the project after Cursor appeared.
- I published on my blog technical articles about fundamentals (vector databases, RAG), assisted development (agents, prompt engineering, context/memory management), and tooling (MCPs, Figma integration with AI).
- I developed Claude Talk to Figma, an MCP server that allows Claude to read and modify Figma designs, facilitating AI integration into design workflows.
