What I'm
Focused On
A live snapshot of where my energy is going — the studies, certifications, projects, and publications that occupy my attention right now.
AWS Cloud Security
Architecting and securing cloud-native infrastructure on AWS — IAM hardening, security posture management, and building resilient, scalable environments.
AI-Driven Automation
Building end-to-end business and security process automation with n8n, LangGraph, and AI pipelines — turning repetitive manual work into intelligent, self-running workflows.
Offensive x Defensive x Audit
I help organizations understand how they will be attacked, prove it, and fix it end-to-end across engineering and governance.

The
Intersection
Security sits at the intersection of technology, people, and business.
My work spans offensive testing, defensive engineering, cloud security, and audit, but the goal is always the same: to understand systems completely and make them hold under real conditions.
“I focus on building scalable processes, not just fixing isolated issues.”
Because security that does not scale will eventually fail. And security that ignores human behavior and business realities was never complete to begin with.
