About

I am a motivated individual who enjoys working with people. I have vast 8 years’ experience in Networks/Servers infrastructure (Windows Servers, VMware vSphere, Sonicwall firewalls). I am detail orientated and that allows me to resolve issues efficiently. I deal with senior and junior staff in my day to day work.
