I come from a systems-first background, with solid hands-on experience in Linux and Windows environments, virtualization, and containerization.
I am currently focusing on cybersecurity, building offensive security skills on top of a strong systems foundation.
My learning style is practical: I work directly with operating systems, infrastructure, and automation to understand how systems behave, fail, and can be exploited.
🎓 Master in Cybersecurity & AI – Evolve Academy
Pentesting-oriented training focused on:
- Linux and Windows internals
- Networking fundamentals
- Vulnerability analysis
- Enumeration and exploitation basics
- Security methodology and tooling
- Scripting and automation for security tasks
This training path is aligned with the eJPTv2 (eLearnSecurity Junior Penetration Tester) certification as the final objective.
Alongside the master, I actively work on system-level labs, virtualized environments, and containerized services to strengthen my understanding of real-world infrastructure.
I am particularly comfortable working with:
- Linux systems (configuration, services, permissions, troubleshooting)
- Windows systems (installation, optimization, hardening basics)
- Virtualization and lab environments
- Docker and containerized services
- OS-level experimentation and recovery
- Automation and scripting for system tasks
I focus on understanding how systems are built and operated, not just how to attack them.
A Node.js bot that monitors the National Vulnerability Database (NVD) and automatically posts HIGH and CRITICAL severity CVEs to Discord.
Project goals
- Automate vulnerability awareness
- Reduce noise and focus on relevant risks
- Build security-oriented automation grounded in real systems
Key features
- Official NVD API integration
- Severity-based filtering
- Persistent state to avoid duplicate alerts
- Designed for continuous execution (PM2)

- Systems and infrastructure understanding
- Linux and Windows security fundamentals
- Entry-level penetration testing methodology
- Security automation and scripting
- Lab-based learning and controlled environments
I prioritize foundations and methodology over tool spamming.
My goal is to start in cybersecurity roles where strong system knowledge is valued, such as:
- Junior Pentester (entry-level)
- Security-focused IT / Systems roles
- Security operations roles with a technical systems focus
In the medium term, I aim to specialize in:
- Offensive security
- Infrastructure-focused penetration testing
- Automation applied to security workflows
