At Salesforce, I spearheaded the overhaul of our customer churn prediction model dashboard using Tableau, which led to a 15% reduction in at-risk accounts identified within its first quarter. This initiative was critical for our Enterprise Solutions team, as previous manual reporting methods were slow and often missed early warning signs, directly impacting account retention efforts and necessitating a real-time, actionable solution for account managers.

During my tenure, I developed robust SQL queries against Snowflake and PostgreSQL databases, processing multi-terabyte datasets to build a new financial forecasting model that reduced data reconciliation efforts by 30%.

I transform operational complexity into actionable intelligence, a capability I demonstrated by reducing inventory holding costs by 18 percent during my tenure in supply chain management. This reduction stemmed from a custom SQL database I designed to track real time shipment velocity against forecasted demand. My role required translating vague warehouse reports into high impact metrics that guided multi million dollar procurement cycles. By focusing on data architecture rather than mere observation, I successfully optimized resource allocation, ensuring that company liquidity remained stable even during periods of significant market volatility.

During my shift from operations to data analysis, I mastered core BI tools to solve persistent system inefficiencies. Using PostgreSQL, I restructured legacy datasets, which improved query response times by 30 percent for the planning department. I then deployed Looker dashboards to visualize live delivery performance, helping team leads identify bottlenecks that reduced cycle times by 12 percent. I also executed rigorous A/B testing on regional fulfillment patterns, utilizing Power BI to validate which shipping methods yielded the best reliability. These initiatives underscore my ability to synthesize diverse data streams into cohesive, actionable insights.

Fragmented user flow across the primary donation interface at the San Francisco Food Bank hindered conversion rates until a comprehensive audit stabilized the funnel. By applying rigorous A/B testing methodologies and synthesizing disparate data points within Google Analytics, I identified a bottleneck in the checkout process that caused a forty percent drop off. Remedying this required redesigning the user journey based on session recordings and event tracking data. This initiative resulted in a twelve percent increase in conversion frequency over three months, providing me with direct experience in transforming raw web behavior into actionable business intelligence.

Technical rigor defines my approach to data preparation and visualization. During my capstone project using Snowflake and PostgreSQL, I cleaned fifty thousand messy customer records to facilitate accurate churn modeling, reducing query latency by twenty percent through optimized indexing. I leveraged Tableau to build an interactive dashboard that tracked key performance indicators, allowing users to visualize demographic trends across different segments. Additionally, I implemented Looker to automate monthly reporting tasks, which saved ten manual hours every cycle. These projects honed my ability to translate complex database schemas into intuitive visual assets for internal stakeholders.
