At IPLAM in the Prefeitura de Maceió, I build ETL pipelines, cloud data environments, and Power BI reporting that turn operational data into reliable decision support. I reduced manual execution for the Negócio da Grota talent-bank workflow from seven minutes to less than one minute using Apache Airflow.

I implement PySpark and SQL transformations for entrepreneurship-event sales analysis, model relational databases to replace spreadsheet-based processes, and structure Azure Data Lakes using Bronze, Silver, and Gold layers. I also publish dashboards and indicators with Power BI and Microsoft Fabric.

Previously at Next Opinion, I migrated educational data from Excel to PostgreSQL with Python, Pandas, and Airflow, and built PHP and SQL functions that increased SCORM course ZIP extraction from 0% to 100%. At ALICC, I configured Azure Files, deployed Docker containers for PHP and MySQL applications, and helped raise IT support satisfaction from 65% to 95%.

I'm currently studying Computer Science and bring hands-on experience with Python, SQL, Azure, Spark, Airflow, dbt, and Data Lake and Data Warehouse architectures.
