  • Unlocking Sales Insights Through Data Visualization with Tableau

    Despite strong product quality and market presence,The company lacks a unified, data-driven view of how its products, salespeople, and delivery strategies are performing across Europe. The leadership team is particularly concerned about underperforming cities, inconsistent delivery statuses, and the need to align pricing, promotion, and product mix with evolving customer behavior. They need actionable insights to optimize sales strategy, delivery efficiency, and regional performance. I leveraged data to drive strategic decisions across sales and marketing. My work involved a deep dive into sales performance, where I pinpointed high and underperforming locations by comparing sales volume with delivery success metrics. I evaluated the effectiveness of our sales channels to understand their true impact on profitability and customer transactions. To optimize our sales team's output, I developed performance dashboards tracking individual contributions against a $100,000 profit target. Furthermore, I conducted a product profitability analysis to highlight top margin contributors and compared the performance of organic versus non-organic products across channels. These insights were crucial in shaping our future marketing campaigns, product development roadmap, and overall sales strategy.

    AirBNB performance analysis

    This project involved a comprehensive analysis of business performance data for airbnb company, a dynamic online vacation rental platform operating across major U.S. tourist destinations. The goal was to transform raw operational data into actionable intelligence to support strategic decision-making and identify pathways for sustainable growth. The company, while experiencing growth, lacked a clear, data-driven understanding of its operational strengths and weaknesses. Leadership faced several critical business questions that required investigation: Performance Visibility: There was no clear mechanism to identify top and bottom performers across key dimensions like listings, hosts, and geographic cities, making resource allocation inefficient. Operational Inefficiency: Anecdotal evidence suggested significant revenue loss due to booking cancellations, but the scale, root cause, and impact of this issue were not quantified. Growth Strategy Limitations: The company struggled to understand why some markets (e.g., Washington) thrived while other high-potential markets (e.g., California, New York) underperformed, hindering effective expansion planning. Revenue Concentration Risk: It was unclear if the business was overly reliant on a small number of high-performing listings, creating potential vulnerability. This project was initiated to address these gaps by conducting a deep-dive analysis into sales, revenue, and cancellation data to provide clarity and a foundation for evidence-based strategy.
