About Me

I'm a frontend-focused developer who enjoys building clean, performant web experiences. I work primarily with modern tools like Astro and vanilla JavaScript, but I'm equally comfortable diving into WordPress, Shopify, or setting up the infrastructure to keep everything running smoothly.

Currently working at Esparta Digital, where I lead web development for e-commerce and CMS projects. I also run VANTAG.es, an open-source platform where I experiment with new web technologies and share knowledge with the developer community.

From Málaga, based in Granada, Spain 🇪🇸 • Working remotely.
