Worked for 2.5 years within a Retail Analytics engagement for a global technology client, writing and maintaining complex SQL and MySQL queries, stored procedures, and data extracts against million-row retail datasets to support recurring business reporting and ad-hoc analysis. Designed and maintained Power BI dashboards using DAX measures for KPI monitoring across sales, inventory, and customer metrics, while performing end-to-end ETL — extracting, cleaning, transforming, validating, and loading analysis-ready datasets. Investigated data quality issues, documented root causes and validation rules, and conducted exploratory analysis to surface trends and anomalies, communicating findings clearly to non-technical business stakeholders. Maintained thorough documentation of dataset definitions, dashboard logic, and data dictionaries, and gained exposure to AWS cloud fundamentals while collaborating with cross-functional teams to translate business requirements into accurate, maintainable analytical deliverables.
