From My Sandbox to Yours — Practical IT Insights.
About this site
Welcome to Sandbox99.cc – a space where I share my IT journey, lessons learned, and practical insights. The tagline “Learning IT by Doing, Sharing What I Know” captures the essence of this blog. Every article here is based on my real-world experiences, reflecting what I’ve encountered, solved, and applied in my day-to-day IT work.
Why Sandbox99.cc?
This blog is my digital sandbox – a place to experiment, document, and share the knowledge I’ve gained from hands-on work, training, and personal projects. Unlike traditional resources that might focus on theory, I prefer to write about practical scenarios, offering genuine insights and lessons that others might find useful.
