Read my blog View my work

I am a computer engineer, gamer and loves coffee.

I enjoy solving complex problems and diving into self-guided research.

Over the years, I've built web applications, managed infrastructure, and delivered tier 1 support.

Today, I focus on managing scalable systems like kubernetes while exploring cloud architecture and cybersecurity.

Cheers,

Jayzsec
