At ZS, I operate and troubleshoot AWS EMR batch workloads for multi-terabyte pharmaceutical datasets, and maintain metadata-driven Control-M and Airflow workflows. I also built S3-to-Redshift ingestion with validation, incremental loads, and automated audit logging.
For my Olist E-Commerce Analytics Warehouse & Dashboard project, I built a DuckDB warehouse with dbt models and tests, then developed a Plotly Dash dashboard with six KPIs and seven charts. I’ve also built a customer churn analytics pipeline and a battery health estimation platform using Kalman filtering, LSTM, and Random Forest models.
