About me

Sinfonía Digital

• Hello! My name is Miguel Martínez and I am a freelance web designer based in Barcelona. I work with small and medium-sized enterprises (SMEs) to design your online presence and boost your business.

• The website should serve as a gateway for new clients. Therefore, SEO positioning on Google is crucial. A website without good positioning is like a store in the desert; no matter how beautiful it is, it won't attract customers. My web designs are focused on ensuring that your potential clients find you before your competitors.

• As a freelance professional, I can offer you competitive prices since I don't have structural expenses to pass on to my clients, as agencies do.
