I'm Carlos. I build things on the web.

I started in business administration, but my whole career has lived at the intersection of marketing and technology. For the past 5+ years I've led SEO and web development at Dualthink for clients across aesthetic medicine, premium hospitality, specialized e-commerce, and the public sector.

In the last two years I've doubled down on AI development. I got Anthropic-certified in Claude Code and finished a Master's in AI at Founderz. Today most of what I ship combines AI workflows with traditional dev — faster output, same quality.

When I'm not on client work, I'm building my own products: Qrusty (live), Puppitos (paused), and a handful of internal tools.

I work from Spain in Spanish, English, Galician, and Portuguese.
