End-to-end Tableau Cloud dashboard built for a US cybersecurity company to monitor automated scanner findings across penetration testing operations. Connected to BigQuery as the primary data source, combining multiple production tables through custom joins and calculated fields to deliver a unified view of findings volume, severity distribution, rejection reasons, and task tracking.
The solution includes multiple views — an executive summary with high-level KPIs, detailed breakdown screens by severity, scanner tool, and scan level, and time-series analysis of findings trends by week. Designed to support both operational monitoring and strategic decision-making across security and product teams.

Tester Performance Profile Dashboard — Cybersecurity Operations
Individual-level performance dashboard built in Tableau Cloud for a US cybersecurity company, designed to drill down into tester profiles identified as outliers (top and low performers) through upstream statistical models. The dashboard is accessed via navigation from a higher-level overview that detects anomalies, enabling a seamless workflow from population-level insight to individual analysis.
Connected to BigQuery across multiple tables, combining test activity, findings, contracted hours, ratings, and qualitative feedback (positive/negative tags) through calculated fields and dynamic parameters — including a username parameter that filters the entire view to a specific tester on demand.
Provides a comprehensive view of individual performance: total tests, contracted vs. active hours, findings by criticality, methodology breakdown, carry-over findings, peer ratings, and trend lines across time. Supports both operational review and talent management decisions within the security team.
