Pragmatic Verification
Security isn't a state of being; it's a continuous process of verification, logging, and hardening. I deliver clear proof-of-concept exploits paired with actionable remediation reports.
Offensive Analysis
Defensive Remediations
I identify critical attack paths by chaining minor vulnerabilities together, simulating real-world threat actors to expose structural weaknesses before they are exploited.
I secure cloud environments through zero-trust architecture and optimized SIEM ingestion, ensuring your security operations team has absolute visibility over every asset.
