At Fullphi S.A., I supported the ITALCRED, IAPSER, and EDESA campaigns, handling customer inquiries and complaints across channels. I achieved 95% first-call resolution.

I also reduced average handling time by optimizing scripts and case classification. For complex cases, I escalated them to technical teams and followed up through resolution.

At Atento S.A., I handled inquiries and complaints for the Fiserv campaign, analyzed online accounts, and processed tasks including card activations, reports, and travel registrations.

Since 2011, I’ve sold national and international products online using digital platforms and social media, including live-streaming e-commerce. I’ve also managed my own business, with responsibility for staff, stock, sales, and customer retention.
