I'm a technology professional focused on cybersecurity, with interests spanning offensive security, embedded systems, operational technology (OT), and threat intelligence.

My current focus is building practical knowledge through hands-on labs, security research, projects, and continuous study.

• Offensive Security
• Penetration Testing
• Reconnaissance & Enumeration
• Web Security
• Network Security
• Embedded Systems Security
• OT / ICS Security
• Threat Intelligence
• OSINT
• Security Automation

• C / C++
• Python
• Bash
• PowerShell

• Linux
• Windows
• Embedded Systems
• Virtualization

• Penetration Testing
• Network Security
• Web Security
• Vulnerability Assessment
• Reconnaissance
• Threat Intelligence
• OSINT

I'm building and maintaining hands-on cybersecurity environments to study:

• Pentesting methodologies
• Network security
• Windows & Linux environments
• Active Directory
• Web application security
• Wireless security
• Embedded systems
• OT / ICS security
• Attack simulation
• Defensive controls
• Threat intelligence

All offensive security activities are performed in controlled, authorized environments for educational and research purposes.

• Penetration Testing
• Offensive Security
• Web Security
• Reconnaissance
• Network Security

• OSINT
• IOC Analysis
• TTP Analysis
• MITRE ATT&CK
• Threat Actor Research

• Embedded Systems Security
• OT Security
• ICS Security
• Industrial Networks

Projects related to penetration testing, reconnaissance, vulnerability assessment and security research.

Hands-on environments designed to study attack and defense techniques in controlled systems.

Research and experimentation involving embedded devices, industrial protocols and operational technology.

Research involving OSINT, threat actors, indicators, TTPs and intelligence analysis.

I document what I learn through:

• Technical notes
• Lab reports
• Security research
• Write-ups
• Methodology documentation
• Project documentation

Building toward a career in Cybersecurity, with a long-term focus on the intersection of:

Offensive Security × Threat Intelligence × Embedded/OT Security

with the goal of working toward Industrial Cybersecurity.

All security testing, exploitation and offensive security research published here is performed against systems I own, intentionally vulnerable environments, or systems for which I have explicit authorization.
