Making data speak

I've spent 5+ years building Business Intelligence, automation, integration and data analysis solutions — across contact center operations, continuous improvement, and now the banking sector. Along the way, I migrated legacy systems to the cloud, optimized queries with gains of up to 60% in execution time, and implemented validations that reduced operational penalties for missed deadlines.

I cover the full data cycle: extraction and transformation in Python and SQL, large-scale processing with Databricks and BigQuery, and final delivery in executive Power BI dashboards focused on storytelling and strategic KPIs. I also mentor junior and mid-level analysts on data best practices, performance and architecture.
