Iv been working in the IT field for more than ten years. I have started as an help-desk technician, infrastructure support and systems integrator/consultant, datacenter tech and network operations engineer. I’m passionate about networking and security. I’ve spent the last two years working in a datacenter taking over 600+ servers and network equipment in a senior position.

I will be updating my blog the best i can, (time is an issue), sharing information about my studies and research i’ll be conducting along the way. Hope you can find useful information. My belief is that knowledge is meant to be shared, so whatever it is that I’m aware of, I’ll share with you. Please feel free to contact me for any reason.
