About Jules

I bridge the gap between enterprise security operations and emerging Web3/AI threats. Unlike traditional sysadmins, I operate at the intersection of defensive SOC operations and offensive blockchain security—delivering MITRE ATT&CK-aligned detection engineering for Fortune 500s while auditing smart contracts for DeFi protocols.

RECENT ENGAGEMENTS:
• Atos (Eviden) — SOC Consultant: MITRE ATT&CK detection use-cases, ELK/Splunk SIEM tuning, Check Point firewall analysis, incident investigation with Kibana dashboards
• LeasePlan — Security Administrator: AS400/IBM-i security hardening, API security governance, NIST CSF alignment, Splunk optimization
• Paccar IT Europe — JT Security Specialist: Ransomware recovery validation (Rubrik forensics), Sumo Logic SIEM investigations, Cortex XDR, Azure cloud audit frameworks

CORE EXPERTISE:
• SOC & Detection Engineering: Splunk, Microsoft Sentinel, ELK Stack, MITRE ATT&CK framework, threat hunting, incident response, forensic analysis
• Cloud Security: Azure (AZ-500 certified), Zero Trust architecture, Entra ID, Intune EPM, hybrid identity protection
• Blockchain/DeFi Security: Smart contract auditing (Slither, Mythril), flash loan attack analysis, oracle manipulation research, staking protocol security, responsible disclosure
• AI Security: AI-assisted SOC automation, LLM security research, local inference stacks for security tooling

WHY ME?
I translate technical attack paths into business language for stakeholders—delivering Service Level Reports (SLRs) and governance workshops that satisfy both auditors and developers. Methodical, independent, and attack-path oriented.
