I'm a Barcelona-based freelance AI developer and consultant, building practical AI solutions at the intersection of technology and real-world business operations. Through FenxLabs, I develop enterprise-grade AI products — including AskARC, a multi-model router that reduces AI costs by 40–80% while maintaining EU-grade privacy compliance. I work independently with SMEs and SMBs to identify where AI can meaningfully automate processes, reduce overhead, and unlock new capabilities — taking engagements from initial consultancy through to full technical delivery.
