## About

```text
At Health Catalyst, I contribute to DOS-to-Ignite migration projects, including schema transformations, platform enhancements, and post-migration data reconciliation.

I support client onboarding and source implementations, including Epic upgrades and dynamic table ingestion. I also troubleshoot ETL failures across Databricks, Azure Data Factory, and SQL Server production pipelines.

I build Python and PySpark automation scripts and reporting solutions to improve monitoring and reduce manual effort. I also assist teammates with query tuning and pipeline debugging.

Previously, at Tata Consultancy Services, I supported British Telecom applications including Siebel CRM, Arbor, Glan, and Hyperion. For my BITS Pilani AI & ML capstone, I designed and built DeepGuard, a deep learning system for detecting deepfake videos, with a Streamlit application for video uploads and results.
