『 ABOUT 』

CYBERSECURITY · PROGRAMMING · SYSTEMS

Cybersecurity professional with a background in systems administration, security governance and technical operations. I work across security assurance, offensive security, cyber intelligence and practical security engineering, combining structured risk analysis with hands-on technical work.

Python is a central part of my work: I build utilities, automate analysis and develop tools for security testing, OSINT and data processing. I also work with Java, JavaScript/TypeScript, SQL, Linux and Windows environments. My background in psychology adds a human-factors perspective to security, risk and decision-making.
