Mateo on computer

Hello World! My name is Mateo and I have been interested in working in the world of technology since I was a kid. When I held my first Gameboy I was so amazed on how this little handheld device could play all these games. When I got older my interest in computer science grew. I wanted to know how computers worked and displayed my video games. I later went to community college where I earned my degree in computer programming in December of 2025. This gave me the foundational knowledge of programming logic/languages, networking, databases, operating systems, and how computers work in general. I took the time on my own to learn more things like system/cloud administration, Infrastructure as Code, and how to setup this website from scratch. I am eager to learn new things and really enjoy it. I made this entire website from scratch using only HTML, CSS, and Bootstrap. To experiment with different things of course I also made my own homelab! My goal is to become a system/cloud administrator, cloud engineer, or security administrator.

My Homelab

Hybrid Enterprise Infrastructure & Cloud Automation

My home lab is a dedicated environment designed to simulate enterprise-grade hybrid cloud architectures, serving as a sandbox for testing Zero-Trust networking, Infrastructure as Code (IaC), and secure virtualization.

The On-Premises Core

The foundation of my lab is a secure multi-node environment built on Proxmox VE, hosting a domain simulation with Debian/Fedora Linux and Windows Server 2022.

  • Network Security: Architected a multi-zone network featuring an OPNsense Security Gateway to manage inter-VLAN routing and stateful packet inspection.
  • SIEM/IDS: Implemented a centralized Network Security Monitoring (NSM) solution to monitor cross-VLAN traffic by integrating Suricata with Wazuh (SIEM), enabling real-time alerting for signature-based threats and spoofed internal IP addresses.
  • Zero-Trust Management: Implemented a Tailscale Mesh VPN using encrypted WireGuard tunnels for secure out-of-band management.
  • Automation: Refactored custom Bash and PowerShell scripts into Anisble Playbooks to automate routine security patching, system state reporting, and administrative alerts via SMTP.
  • Containerization: Deployed containerized web server/cloud server using apache2/nextcloud, within a production Docker/Podman environment, including a prod/dev container system, ensuring process isolation, efficient patching, and efficient resource allocation for self-hosted infrastructure.

Cloud & DevOps Integration

Beyond physical hardware, I leverage the lab to master modern DevOps workflows and cloud governance within the Azure ecosystem.

  • Infrastructure as Code: Utilized Terraform (HCL) and Azure Bicep to automate the provisioning of secure, production-ready Azure environments.
  • Secure Access: Engineered a secure networking architecture featuring a Virtual Network (VNET), dedicated subnets, and Azure Bastion for secure management.
  • Automated Security: Implemented automated security configurations, including Network Security Groups (NSGs), to enforce least-privilege access standards.
  • Version Control: Utilized Git and GitHub for version control of infrastructure templates to ensure consistent and repeatable deployments.
