Hi, I'm
Alejandro Bayón
Frontend Developer specialising in accessible component systems, AI-augmented workflows and modern web standards.
About Me
I'm a Frontend Developer with one clear mindset: technology never stops, and neither do I. What truly defines my profile is my obsession with optimising the development workflow. I consider myself a technological early adopter — I integrate Artificial Intelligence (Agents, MCP, Vibe Coding) at the core of my daily work, not just to ship faster, but to raise the quality of solutions and reduce technical friction.
Currently I build complex components within the Open Digital Services (ODS) ecosystem for clients such as Banco Santander, Openbank and Zinia, ensuring scalability and full accessibility compliance (WAI-ARIA). I'm always looking for the next tool that brings real value to both the product and the team.
