// FILE: 01_PROFILE.md

I operate in the space between code and consequence. My career is dedicated to engineering systems that withstand the most sophisticated threats while gathering the intelligence needed to stay ahead of them. Previously, at Cloudflare, I focused on Centralized Advanced WEB and Application Security. I specialize in architecting resilient, distributed systems with a focus on Zero Trust security models, cloud-native infrastructure, and advanced network analysis. My work is precise, my methods are discreet, and my objective is always operational superiority.

> Core Principles: Zero Trust Engineering

Systemic Trust Nullification: The architectural principle that all implicit trust is actively and continuously voided by design.
Just-In-Time (JIT) Access Apertures: The practice of creating temporary, cryptographically-secured pathways for data access that exist only for the duration of a single, authorized session.
Composite Identity Authentication: The mandate that a valid identity is an aggregation of multiple real-time signals, including user, device posture, and behavioral analytics.

> Specialization: Critical Infrastructure Protection

Beyond conventional cybersecurity lies the critical discipline of protecting the foundational infrastructure that powers our industries and governments. My expertise in Critical Infrastructure Protection (CIP), validated through the OPSWAT Academy, is built on a non-negotiable principle derived from Zero Trust: data entering a secure environment must be assumed malicious and neutralized before it can execute.

This is not a passive defense. It is an active strategy of Threat Prevention, employing advanced methodologies like Deep Content Disarm and Reconstruction (Deep CDR) to deconstruct every file, sanitize it of potential threats, and rebuild it as a safe, usable copy. This ensures that only secure data ever reaches its destination, eliminating attack vectors that traditional detection-based models can miss. My proficiency covers the full spectrum of this discipline, from architecting secure data flows to mastering the core engines that power this next-generation defense.

OPSWAT Data Transfer Security Associate Badge

OPSWAT Data Transfer Security Associate (ODSA)

Mastery in engineering secure data pathways. This certification validates expertise in designing and implementing policies that treat all data in motion as a potential threat, using advanced techniques to sanitize every file transfer, from portable media to web uploads, ensuring the integrity of the secure network.

OPSWAT Network Security Associate (ONSA)

Expertise in architecting Zero-Trust network environments for critical infrastructure. This certification demonstrates the ability to implement robust network segmentation and threat prevention strategies that prevent lateral movement and protect critical assets from both internal and external attacks.

OPSWAT MetaDefender Core Professional Badge

OPSWAT MetaDefender Core Professional (OMCP)

Hands-on mastery of the OPSWAT MetaDefender Core engine. This certification represents deep, practical expertise in deploying and managing the advanced threat prevention technologies at the heart of CIP, including Multiscanning, Proactive Data Loss Prevention (DLP), and Deep CDR.
