At IBM, I build and monitor ETL/ELT pipelines with BigQuery, Dataflow, and Cloud Composer, maintaining 99.9% data availability for analytics users. I also work with actuaries and data scientists to turn business requirements into reporting specifications for claims ratios and churn rates.
I cut cloud infrastructure costs by 25% through performance tuning and improved query speeds by 40% with data modeling for a SaaS platform. I also troubleshoot legacy transformations, design warehouse schemas, and set up data quality checks for financial reporting and customer behavior analysis.
