What I'm looking for

I'm interested in product analytics and AI-enabled data solutions, including work involving LLM evaluation.

At Cognizant Technology Solutions, I analyzed high-volume transactional data using SQL, SAS, and Excel to support reporting, validation, and business decision-making. I also investigated data issues and anomalies, then developed Excel and Power BI reports and dashboards with operational KPIs.

In my analytics projects, I worked with retail transactions and airline passenger records, applying data preparation, validation, exploratory analysis, and customer analytics. I developed an interactive Power BI dashboard with DAX-based KPIs and explored Generative AI and LLM-based workflows for insight generation.
