"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.
