Me

About

Based in Lucena (Córdoba), Spain. I joined Conecta Turismo in 2012 as its first employee and helped grow it into a SaaS business serving 95+ clients, leading the frontend across 200+ projects for the travel industry. I take technical ownership of what I build, from architecture to production, and I prefer pragmatic solutions over fashionable ones. Outside work I build my own products: AI Color Analysis, Envilo and Sembalia, each designed, shipped and run end to end.
