Dec 1, 2025Month: 2025-12 Overview: Focused delivery on expanding asset-group tagging capabilities and stabilizing asset-group operations in SpecterOps/BloodHound. Delivered API enhancements enabling advanced asset discovery, richer filtering, and robust documentation/testing, complemented by fixes to a UI workflow impacting owned asset groups. The work reinforces business value by accelerating asset discovery, improving data fidelity, and ensuring reliable user workflows for security teams. Key deliverables and impact: - Asset Group Tags API Enhancements: introduced selector type counts, kind filtering for selectors, asset_group_tag_id filtering in global search, and Count by Kind for Selectors. OpenAPI docs updated; tests expanded to cover new behaviors. - Global search and discovery: enhanced global search to filter by tag IDs and to surface precise asset group memberships, improving accuracy and time-to-insight for asset management. - UI/UX stability for owned asset groups: fixed right-click context menu when adding nodes to owned asset groups to ensure auto-certification configuration works with defaults, reducing workflow friction and configuration errors. - Quality and maintainability: expanded unit tests, refreshed mocks, and addressed PR feedback to improve reliability and future maintenance. Performance improvement included optimizing GetAssetGroupTagSelectorCounts in the DB for faster responses. Technologies/skills demonstrated: REST API design and enhancements, OpenAPI documentation, comprehensive testing (unit/integration), DB query optimization, test mocks, UI workflow stabilization, and cross-team collaboration through PR feedback.
