Bridging Operations,
Security & Automation

Transitioning from a cybersecurity and operations background to modern DevOps practices.

I'm an operations professional moving into DevOps, with CEH, CCNA, RHCE and MCSA certifications. I have been in customer support and operations since 2018, handling everything from system troubleshooting to day-to-day technical support.

I believe in hands-on learning. I build labs from scratch, document them meticulously with architecture diagrams and READMEs, and learn by breaking things on purpose and fixing them properly.
