Denys Kulygin developed and maintained security analytics integrations for the Azure/Azure-Sentinel repository, focusing on NordPass telemetry and threat detection. Over five months, he delivered end-to-end features such as activity log ingestion, analytics rules for data breach detection, and asset management updates, using Go and YAML for backend development and configuration. Denys addressed code hygiene by refactoring, sanitizing inputs, and correcting documentation, ensuring maintainability and compliance. He also managed decommissioning of deprecated components to reduce risk and streamline architecture. His work demonstrated depth in cloud integration, security monitoring, and DevOps, resulting in robust, reliable solutions for enterprise security operations.

Month: 2025-08 Key features delivered: - NordPass Analytics: Domain Data Breach and User Data Breach Rules (v3.0.1 release) implemented for Azure/Azure-Sentinel. Updated NordPass package to v3.0.1 with accompanying release notes. Linked commits: 641414f0f786c0990a33c8052c89245af7a72895. Major bugs fixed: - Fix: Non-ASCII apostrophe in analytics rule description YAML to ensure accurate representation and parsing. Commit: 930409b6a78937bdd2a3ccfd73a8b9a947c302ff. Overall impact and accomplishments: - Strengthened threat detection by adding two analytics rules that surface domain and user data breaches on the dark web, enabling faster incident response and risk prioritization. The YAML parsing fix improves rule reliability and reduces deployment-time issues. Release notes accompany the v3.0.1 package update to support customer onboarding and IT hygiene. Technologies/skills demonstrated: - Security analytics development, YAML-based rule configuration, packaging/version management, and release documentation. Demonstrated attention to data representation (non-ASCII handling) and robust change control.

Month: 2025-07 — Data Connectors Decommissioning completed in Azure/Azure-Sentinel. The work involved deprecating and removing the Data Connectors project by deleting all source code, dependencies (go.mod/go.sum), and configuration, effectively removing its functionality. This cleanup aligns with architectural simplification and regulatory/security requirements, and it reduces ongoing maintenance and potential risk from unused components.
