I’m a Data Analyst with 2+ years of experience using SQL, Python, Excel, Tableau, and Power BI to analyze operational and customer data, build dashboards, and support business reporting initiatives.

I’m strongest in writing complex SQL queries, cleaning and validating datasets, troubleshooting data inconsistencies, and translating technical findings into actionable insights that teams can use immediately.

In my recent role, I analyzed large operational datasets to reduce discrepancies by 20%, and I built interactive Power BI and Tableau dashboards that cut report latency by 45% while increasing adoption by 30%. I also implemented automated ETL pipelines and data validation workflows, reducing errors by 38% and improving pipeline reliability by 25%.

I collaborate with cross-functional stakeholders to document reporting logic and validate KPI definitions, and I support ad-hoc analysis to improve data quality and governance. Earlier, as a Graduate Assistant, I optimized scheduling for 5,000+ students, improving efficiency by 22% and reducing exam conflicts by 35%, while automating recurring reporting to cut preparation time by 30%.
