What I'm looking for

I’m looking for a role where I can build reliable, large-scale ETL/ELT pipelines and automate reporting with Python, SQL, and Spark—partnering closely with business and risk stakeholders to improve data integrity, validation, and decision-making.

I’m a Data Engineer/Analytics Engineer with 3+ years of experience building and improving data workflows in the financial sector. I specialize in translating business requirements into practical technical solutions, with a strong focus on data reliability, process efficiency, and validation for risk-related processes.

At Santander Brasil, I automated recurring financial reports with Python and SQL, developed statistical validation models to strengthen internal data reliability, and built Spark-based data pipelines handling 100M+ records in critical workflows. I also created Power BI dashboards to reduce manual processing and supported compliance and audit activities by improving data integrity across reporting flows, and I’ve continued that focus while pursuing an MBA in Data Analytics and Artificial Intelligence.
