In my previous role, I was tasked with analyzing a multi-year dataset of financial transactions to identify spending patterns. I used SQL to query the data and Excel for visualization. By segmenting the data by department and time period, I was able to identify a significant increase in procurement costs over the past two years, which led to a recommendation for a more stringent approval process for high-value purchases.

I follow a rigorous process of cross-checking data sources, validating calculations, and conducting peer reviews. For instance, when preparing a quarterly financial report, I double-check all formulas in Excel, verify the data against the source systems, and have a colleague review my work to catch any potential errors before finalizing the report.

I am proficient in SQL for data extraction, Excel for data manipulation and visualization, and Tableau for creating interactive dashboards. Additionally, I have experience with Python for more complex data analysis tasks, such as predictive modeling and machine learning applications in finance.

I focus on simplifying the message by using clear, concise language and visual aids like charts and graphs. For example, when presenting a financial forecast to the executive team, I would highlight key trends with a few select charts, explain the implications in plain language, and provide a summary slide with actionable recommendations.

In my last position, we transitioned from an outdated reporting system to a new ERP platform. I took the initiative to learn the new system quickly by attending training sessions and working closely with the IT team. Within a month, I was able to generate accurate financial reports using the new system, which improved the efficiency and reliability of our reporting process.
