BrazilWhat I'm looking for
I’m a customer service and technical support professional with experience delivering high-quality support, handling issues, and maintaining strong client relationships in dynamic and international environments. I bring multilingual communication skills and a problem-solving mindset to every interaction.
In my recent administrative assistant role, I focused on client satisfaction and retention, building strategies to optimize operations and managing relationship workflows with business partners. I supported business decisions through business analysis, spreadsheet creation, and KPI tracking, using data to identify improvement opportunities.
Earlier, I worked as a bilingual support analyst providing technical support for advertisers, collaborating directly with global engineering teams and managing data for smoother operations.
