Data analyst turning governed data into forecasting insights.
BrazilWhat I'm looking for
I’m a Data Analyst with 5+ years delivering end-to-end analytical solutions—ETL pipelines, dimensional modeling, and interactive dashboards tied to actionable business KPIs. I’m known for bridging technical and business teams so decisions move faster and operational overhead drops.
In my current role as a Senior BI Analyst at Cyrela, I built a churn prediction model that reached 80% accuracy and was adopted by the commercial team to drive proactive retention actions. I also created a dashboard versioning structure using dimensional modeling and governance practices to maintain data reliability and traceability.
Before that, I led automation initiatives at Cyrela—cutting a manual finance reporting cycle from 2 days to 2 hours using an Apache Airflow pipeline on AWS, and centralizing KPIs across operational and executive stakeholders with Power BI and Microsoft Fabric. Across projects, I’ve delivered forecasting and ML pipelines (ARIMA, Prophet) and strengthened data foundations with tools like dbt, SQL optimization, and data governance.
