I have over 20 years of experience in computer troubleshooting, networking and repairs as well as electronics. I can answer questions concerning Windows Server 2003/2008/2008R2 and 2012. Hardware repair and upgrades as well as questions regarding Windows XP/7/8. I have also developed a speciality with Hyper-V the last year. If I don't know it, I will try my very best to find the answer.

Experience in the area

I have worked both as a Technical Director and Information Technology Manager and I also operated a home-based computer consulting business for many years, which included the installation, update and security of computer systems and Windows servers. I have also drafted many IT Plans and consultation reports for specific recommendations.

My experience ranges from Project Planning to finding different networking solutions for companies. My work has demanded that I keep informed and this has always allowed me to be proactive by keeping up to date with technology; this involves researching and learning on a day to day basis, which I find to be fundamental.

I have also co-produced and edited a number of films so I can offer a vast knowledge on the subject.

Currently Studying for CISSP (2016)
