Back to original languageAbout Xavier
I build and deploy AI agents, automations, and websites for Spanish SMEs, with a specialization that few cover: technical integration with Spanish tax regulations (VeriFactu/AEAT, Facturae).
I work on the intersection that matters: product (Next.js/React), automation (n8n + AI agents, custom API), and compliance (verifiable electronic invoicing). I deliver quickly and connect to your current stack (Holded, A3, Sage, Stripe) without you changing providers.
What I do for you:
Custom VeriFactu / Facturae integration on your website or ERP.
n8n automations: lead→CRM, reminders, internal processes, scraping.
AI agents via voice and WhatsApp that attend 24/7.
High-conversion Next.js landing pages and dashboards.
If you need someone who understands both code and the Spanish fiscal context, that's me.
