About

I build systems that make teams 10x more effective - not by replacing human judgment, but by amplifying it. The principle driving everything: if your AI use makes people feel you put in less effort, you're doing it wrong. My background combines deep technical capability with strategic systems thinking. Examples of systems I've built: * App Store Catalog (ML-powered cross-platform targeting): Scraped all major CTV app stores and used AI to solve the fragmentation problem - a single app like CNN exists with different IDs across Apple TV, Roku, Samsung, etc. Built unified taxonomy that maps all variants to canonical apps and categories, enabling advertisers to target "CNN" or "News" across all platforms with a single command. Included OTT detection logic using app store signals (full-screen capability, etc.) to distinguish true streaming apps from mobile apps. This catalog was integrated into Criteo's platform reporting and adopted by IponWeb for BidSwitch. * Audience Processing Infrastructure: First non-R&D person at Criteo to use PySpark on Hadoop for production workloads - processing audiences of 300+ million IDFAs (all clothing buyers in Australia, etc.). Built system that reduced processing time from 3 days to under 9 hours after R&D said the approach wasn't feasible. Created repository and infrastructure used by whole company. My background spans operations, development, sales, and management - which means I see the whole machine, not just individual parts. I build solutions that work because I understand what R&D considers feasible, what sales needs to close deals, and what ops can actually execute. This cross-functional perspective has enabled me to build systems that R&D initially said were impossible, that commercial teams actually adopt, and that scale operationally. But the most impactful work isn't about the technology itself - it's about understanding where human expertise is irreplaceable and where systems can scale that expertise. I'm interested in the questions most people skip: What makes recipients feel your work is thoughtful? How do we build AI that makes the human contribution more visible, not less? Based in Barcelona. Father of twins. Occasional speaker to crowds of 500+. Always happy to discuss AI strategy, go-to-market systems, or why solving fragmentation problems matters more than yet another chatbot.
