We began with a focused security review of every endpoint that handled PHI. We tested for data exposure in API responses, browser caching of sensitive data, and unauthorized access through permission escalation. This produced a prioritized list of 23 vulnerabilities.

Worked with the client data science team to build a test dataset of doctors and trials with known correct matches. We ran the algorithm against this dataset and flagged any mismatches, false positives, or ranking anomalies for investigation.

Built a comprehensive test evidence package mapping each HIPAA and SOC 2 requirement to specific test results. This included screenshots, API response logs, and encryption verification reports that the client used directly in their audit submission.

Load tested the search system with realistic query patterns to verify response times stayed under 2 seconds even with complex multi-criteria filters. We identified and reported an N+1 query issue that was causing search slowdowns for users with large result sets.
