Senior Data Analyst
- Gathered requirements directly from clients and translated them into BI solutions: modeled star-schema data warehouses and built OLAP cubes (Pentaho/Mondrian), queried via MDX to power interactive HTML dashboards and ad hoc reports.
- Designed and automated ETL pipelines and operational workflows using Pentaho Data Integration (jobs & transformations), including dataset validation, log monitoring, and automated alerting — improving data reliability across products.
- Engineered a geolocation data pipeline (Google Geocoding/Places APIs) under strict budget constraints for a predictive-default model built for a top auto insurance product, orchestrating multiple accounts to work within API rate limits.
- Solved a production performance bottleneck that indexing couldn't fix by re-architecting spatial point-to-region lookups in Elasticsearch, enabling a feature that helped the product become one of the company's top performers.
- Designed and delivered an 8-module internal training program on Pentaho Data Integration, onboarding new team members on ETL development from fundamentals to advanced patterns.
