At Grupo Portfolio, I owned a public-sector conversational assistant that helps citizens query public-spending data. Its orchestrator routes requests to five specialized agents grounded in 11 data sources.
I defined and tracked AI quality measures, including precision, context relevance, and p90 latency. By iterating on prompts and agent behavior using real usage, I improved answer precision from 78% to 94%.
At nashai.ai, I owned product strategy, discovery, and roadmap for an enterprise procurement and supply-chain platform. An internal purchasing module rolled out to 3,000+ Raia Drogasil pharmacies, improving operational efficiency by 40% and cutting the purchasing cycle from 28 to 12 days with zero compliance deviations.
At Contele Soluções Tecnológicas, I managed fleet management, field operations, and ERP products across web and mobile. I also worked on UX strategy and onboarding; redesigning critical field-operations flows reduced support tickets by 23%, while onboarding changes increased early adoption by 35%.
