About

Security professional with a background built across regulated financial and security environments

At Mastercard, I worked in cryptographic key lifecycle management and PKI operations, handling certificate workflows, key exchanges, and PCI-DSS compliance in a strict dual-control environment. At Binance, I worked in the KYC department, focusing on threat detection and fraud investigation - conducting OSINT, enhanced due diligence, and risk escalation in a high-volume compliance function.

In 2025 I completed a 6-month cybersecurity bootcamp covering SOC workflows, SIEM operations, DFIR, MITRE ATT&CK, and red team methodologies. I hold the eJPT (97%) and ISC² CC certifications.

Brussels-based, EU national, open to IT, cybersecurity, and security operations roles - hybrid or on-site in Brussels and remote for broader EU.

Actively developing my skills via CyberDefenders, TryHackMe, Hack The Box, and home-lab projects.
