"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.

AI

2023

Making Science

2024

Making Science

  • 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

Making Science

  • 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.
