Worked on Splunk’s contentctl, security_content, and attack_data repositories, delivering seven features over four months focused on security content automation and threat detection. Developed new CLI subcommands, enhanced MITRE ATT&CK map generation, and introduced S3 bucket monitoring and attack simulation datasets. Leveraged Python, YAML, and JSON to implement robust data models, TypedDict structures, and improved configuration management. Refined data processing and visualization for threat mapping, enabling faster triage and reproducible baselines. Led repository governance changes by streamlining documentation and contribution policies, ensuring long-term stability. Prioritized operational efficiency, data integrity, and maintainability across backend development, cloud security, and detection engineering workflows.
February 2026 (2026-02) monthly summary for splunk/contentctl: Implemented a maintenance-only governance stance with a comprehensive repo cleanup and policy change. Removed external contribution pathways and prepared the repository for long-term stability by deleting CONTRIBUTING.md and removing PR/contribution references across code and docs. This reduces support overhead and avoids confusion among users and potential contributors, while preserving existing functionality and stability.

June 2025: Delivered a richer MITRE ATT&CK enrichment and Attack Navigator integration in splunk/contentctl. Implemented a robust data model, improved processing, and enhanced metadata and Navigator formatting to enable precise threat mapping, faster triage, and auditable detections.

March 2025: Delivered MITRE ATT&CK map generation enhancements for splunk/contentctl, improving data fidelity and usability. Changes include storing detection type, ID, and name separately; constructing per-detection research URLs; and refining the layer JSON for Navigator compatibility. No major bugs fixed this month. Business value: faster, more accurate MITRE mappings enable analysts to investigate and report more efficiently. Technical skills demonstrated: data modeling, JSON schema refinement, URL generation, and clean Git contribution with a focused commit history.

February 2025 monthly summary for the Splunk repositories. Key deliverables across contentctl, security_content, and attack_data improved threat-hunting capabilities and standardized validation, aligning technical work with business value. Highlights include the robust addition of a Contentctl recognize subcommand with a dedicated RecognizeCommand dataclass and improved command/config handling, enhanced feedback tailored to security detection engineering and threat hunting, new S3 decommissioned bucket monitoring with a baseline and two detection rules (shipping as experimental), standardized test data sources and configurations, and the introduction of a baseline dataset for the S3 bucket deletion attack technique (T1485). These changes collectively improve operational efficiency, reduce time-to-detection, and provide reproducible baselines for detections and datasets across the security content workflow.
