What I'm looking for

I'm looking to build scalable analytics solutions, automate workflows, improve data quality, and partner with cross-functional teams to turn complex data into clear operational decisions.

At Optum, I build SQL and Python analytics solutions, interactive Power BI, Tableau, Redash, and Looker dashboards, and dbt/AWS Redshift ETL pipelines. My work reduced data preparation time by 30%, issue-resolution time by 40%, and improved predictive accuracy by 15%.

I've also delivered customer and portfolio analytics at Capital One and transformed more than 5 million records at TCS. I use exploratory analysis, machine learning, workflow automation, and LLMs to surface actionable insights, improve data quality, and help cross-functional teams prioritize high-impact operational improvements.
