Hi, I'm Marco
MSc Mathematics · SOC Analyst @ EY Málaga · building Fraud & Anomaly Detection ML
Featured project: Sentinel — fraud risk-scoring platform
Experience
SOC Analyst — Detection Engineering & Security Analytics
Detection engineering in the SOC: Azure Sentinel Workbooks and KQL on high-volume security telemetry, Logic Apps playbooks for enrichment and risk-based escalation, and Python/Bash pipelines to normalize multi-source logs. Focus on cutting triage time and false-positive noise with statistical anomaly workflows — bridging security operations toward applied ML for fraud and anomaly detection.
Research Student
Research on monotone-preserving cubic/bicubic Hermite interpolants for geometric constraint preservation, with new numerical methods for the bidimensional case ( forthcoming publication track ).
Research Student
Quantitative graph theory: free-group structure via Cayley graphs, combinatorial pattern recognition, and analysis of invariant / symmetry structures.
