What I'm looking for

I’m looking to leverage data to drive operational excellence—improving efficiency, strengthening governance, and delivering reliable reporting. I want to continuously refine processes through automation and data-driven decision making.

I’m a results-driven Data Analyst who validates financial and member data to ensure accuracy and compliance across retirement fund processes. I focus on data integrity by conducting reconciliations, identifying discrepancies, and performing root cause analysis to strengthen data governance.

I use advanced Excel (Power Query, pivot tables, dashboards) and Power BI to clean, transform, and prepare datasets for monthly and quarterly valuation and reporting cycles. I’m also hands-on with automation exposure—supporting workflow logic design, testing, and data validation to reduce manual effort and improve efficiency.

Previously, as a Data Quality Assurer, I ensured the accuracy and consistency of large datasets through data profiling, validation, and quality checks. I built and maintained data quality frameworks and supported stakeholders with data-related queries and best practices, consistently contributing to continuous business improvement through strong attention to detail.
