Who I Am
#

Linux practitioner building toward a cloud engineering role, with a security-first mindset. The goal is clear: Network+, Security+, AZ-900, RHCSA, and AZ-104 in sequence — Linux depth underpinning cloud infrastructure, with security running through everything.

The site documents all of it — certs studied, labs built, infrastructure provisioned and torn down. Security thinking runs through everything here — not as a separate concern but as part of how I approach every system and decision.

A four year electrical installation apprenticeship gave me a methodical approach to systems and fault finding. Years running production lines in manufacturing taught me how real operational environments work under pressure. That grounding informs how I think about Linux, infrastructure, and reliability — systems that have to work, not just work in the lab.

What This Site Is
#

A working journal. Every certificate studied, homelab built, and command line tool configured gets documented here. Written for anyone following a similar path — and for future me when I forget how I did something. If something I document saves someone else an hour of troubleshooting, that’s reason enough to write it up.

The Journey
#

  1. CompTIA ITF+

    Completed

    Foundation certification. The starting point.

  2. CompTIA A+

    Completed

    Hardware, operating systems, troubleshooting, and core support skills. The generalist baseline.

  3. CompTIA Network+

    In Progress

    Networking fundamentals — TCP/IP, subnetting, routing, switching, and network security.

  4. CompTIA Security+

    Planned

    Security concepts, threat analysis, incident response, and cryptography.

  5. AZ-900

    Planned

    Introduction to Cloud Infrastructure

    Microsoft Azure fundamentals — cloud concepts, core services, and the foundation for the Azure administrator path.

  6. RHCSA EX200

    Planned

    RHEL 10

    Red Hat Certified System Administrator on RHEL 10. The Linux foundation everything else is built on.

  7. AZ-104

    Planned

    Azure Administrator

    Azure Administrator Associate — managing and governing Azure infrastructure, and the natural next step after AZ-900.
