At Telefónica | VIVO, I led a team of four in postpaid customer retention and churn prevention. Our retention, activation, and loyalty initiatives cut premium postpaid churn by 50%, supported by targeted campaigns and an AI-driven churn prediction model built with BI.
As Product Owner & CRM Process Owner for Fiber Broadband, I governed the customer journey from sales entry through installation. A CRM data-quality project eliminated registration duplications and lost installation visits, generating R$1.3M in savings within nine months.
