Business Intelligence Analyst

I am responsible for the Data area during the company’s operational expansion, which grew from approximately 18,000 to 80,000 customers following a merger in September 2023. I build interactive dashboards, indicators, and analyses that support executive and business-area decisions, including investigation of operational issues and regional performance differences.

I developed a dashboard to identify CTOs with recurring large-scale failures, helping the Infrastructure team prioritize preventive maintenance and contributing to a 48% reduction in incidents. I also structured Marketing data for lead tracking and investment allocation, integrated data from more than 10 systems and sources, and implemented company-wide customer-service evaluation processes.

I built a Data Warehouse using Python and PostgreSQL to centralize AI-assisted and operational service data, including incremental ETL processes and historical records. I also developed an AI SDR to accelerate commercial service, supported implementation of a voice and chat service platform, and contributed to AI-integrated service workflows.

I analyzed collection indicators and results for major client portfolios, including Energisa, Santander, Bradesco, and Avenida. My analyses supported tactical and operational decision-making for collection operations.

I used SQL to manipulate and validate data, ensuring consistency in the information used by management teams. I documented queries, databases, and business rules to improve traceability and information reuse.

My analytical work contributed to increased agreement volume and collections, supporting operational expansion into new regions, growth of the collection portfolio, and improved business results.

I analyzed and segmented large data sets to direct Vivo offers, helping maintain sales compliance at 95% with the offer recommended for each customer.

I identified performance gaps across teams and supported the definition of actions to improve sales conversion. These initiatives contributed to a 15% increase in overall operational conversion.

I monitored performance indicators and validated operational data to support leadership decisions and improve the quality of operational results.
