Stefano Rodriguez is a seasoned mobile-first technology leader and current CTO based in Milan with 11 years of product and engineering experience spanning startups and scale-ups. He co-founded consumer-focused platforms early in his career and later spent five years at Bending Spoons contributing to core iOS frameworks (Katana-Swift) and robust layout/store improvements. Stefano has hands-on experience building privacy-sensitive mobile features—contributing to Italy’s official Immuni Android app with exposure-detection and notification work—showing an ability to deliver reliable, safety-critical client-side systems. As CTO at Clay he combines product intuition with low-level and high-level engineering skills, from algorithm tweaks to app architecture. Colleagues would describe him as an engineer who still ships code while shaping technical strategy, with a habit of fixing subtle layout and concurrency bugs that others miss.
