PROFILE
Trosenblatt
Thomas Rosenblatt developed and enhanced core backend features for the DataDog/dd-sensitive-data-scanner repository over six months, focusing on scalable, configurable scanning and robust performance monitoring. He introduced parallelized match validation using Rust and Rayon, expanded scan flexibility with wildcard indices, and enabled rule-driven namespace exclusions for compliance-focused customization. Thomas improved event traceability by adding unique event identifiers and streamlined build automation with Makefile refactoring across Go and Rust components. His work also included implementing CPU-centric performance metrics and extending test coverage for asynchronous operations, demonstrating depth in system programming, concurrency, and metrics tracking while maintaining backward compatibility and developer workflow efficiency.

Nov 1, 2025Month: 2025-11 Key features delivered: - Configurable rule-driven namespace exclusions in the scanner: Introduced a mechanism for compiled rules to control whether the scanner processes excluded namespaces. Default behavior remains to process exclusions, but specific rules can override this to prevent scanning of certain namespaces. Major bugs fixed: - None reported this month. Overall impact and accomplishments: - Enables fine-grained, rule-driven customization of the scanning process, allowing compliance-focused rules to tailor scan scope. This reduces unnecessary processing and improves alignment with policy requirements, while preserving backward compatibility by keeping default behavior unless overridden. Technologies/skills demonstrated: - Rule-driven architecture and per-rule configuration integration with the scanner - Commit-based change tracking and traceability (commit 4c74848aa3536a9c41d32da074e14a8b74ac9596) - Code-level collaboration between rules and the scanning engine for enhanced configurability and extensibility.

Aug 1, 2025Month: 2025-08 — DataDog/dd-sensitive-data-scanner delivered a major reliability enhancement for asynchronous scanning by increasing timeout to 60 seconds and adding unit tests to validate timeout handling under slow server responses. The changes reduce scan failures in slower networks, improving security coverage and operator confidence. Key outcomes include extended timeout, expanded test coverage, and improved validation robustness; this supports business value by delivering more predictable and resilient scanning in production.
