about

cat bio.txt

I'm a passionate System Administrator with 8+ years of experience in Linux/Unix environments. I specialize in automating infrastructure, optimizing system performance, and ensuring maximum security.

My journey began as a Linux enthusiast, and today I manage critical infrastructures for enterprises. I believe in the power of open-source and automation to solve complex problems. When I'm not in the terminal, I contribute to open-source projects and write technical blogs.
