I’m a Data Analyst with 1.5+ years of combined experience across healthcare analytics, financial data engineering, and scalable data pipeline development at ZS Associates, BlackRock, and Discover Dollar. I translate large-scale datasets into clear, decision-ready insights using SQL, Python (Pandas, Polars, PySpark), and BI visualization tools like Tableau and Power BI.

At ZS Associates, I synthesized actionable insights from large-scale healthcare claims and clinical datasets (2M+ records) through rigorous exploratory data analysis in SQL and Excel. I also supported Real-World Evidence (RWE) studies by formulating feasibility assessments and cohort analyses—defining patient cohorts, inclusion/exclusion criteria, and data sufficiency benchmarks—while delivering high-integrity outputs through systematic validation and QC checks.

Earlier at Discover Dollar, I architected robust, scalable ETL pipelines processing 10 GB of data by combining PySpark, Polars, and Python, improving end-to-end processing time by 20%. I optimized workflows on Databricks and cloud-based platforms, and integrated Gen-AI capabilities into data engineering to accelerate transformation tasks and reduce manual effort.

At BlackRock, I built a unified Package Production Dashboard in Tableau to consolidate 3+ KPIs, saving stakeholders 5 hours/week. I also improved data reliability and system uptime by engineering exception-handling logic, automated recurring pipelines using Python and SQL, and built configuration-driven integrations with YAML and JSON—backed by hands-on project experience in NLP and computer vision with tools like OpenCV and MediaPipe.
