## About

```text
At Celebal Technologies - CEI, I built ETL pipelines using Python, PySpark, Azure Databricks, and Delta Lake, processing and transforming structured datasets with Medallion Architecture. I also applied SQL joins, CTEs, subqueries, and window functions to analyze data and support reporting requirements.

On my projects, I engineered a PySpark and Databricks pipeline for support ticket data and developed an LLM-powered system for research paper analysis and draft generation. I’ve also built HospitEase, a hospital search and comparison platform with FastAPI, MySQL, and interactive maps.
