Hernán Mammana is a seasoned front-end leader and startup CTO with 15+ years building user-centered, data-driven web experiences from first-page HTML to platform architecture. He scaled and decentralized front-end organizations at Mercado Libre—growing teams from 10 to 70 across countries—and later led engineering and product delivery at Medallia and CookUnity before co-founding Workia. Passionate about design-engineering collaboration, he created reusable UI frameworks (Chico UI) and led cross-functional initiatives like Notifications and Navigation that directly impacted conversion and reuse. A multiplier leader and former professor, he blends hands-on UI craftsmanship (notably strong HTML/CSS contributions on open repos) with hiring, coaching and product strategy. Based in Buenos Aires, he pairs deep practical knowledge of front-end standards since the early web with a track record of shipping resilient, high-performance user experiences.
