SKILLS
ABOUT MARK SUMNER
I\'m an IT Professional with experience of providing 1st to 3rd line support in the IT sector I’m driven and enthusiastic with a real hunger to learn, grow and develop. I’m looking to consolidate my existing skills as well as a acquire new skills.I like to be proactive, fixing issues before they get the chance to become problems further down the line, examples being regularly checking vendor websites (such as HP or Progress) for firmware or software updates as opposed to waiting for emails from the vendors about newly released updates.I believe sharing knowledge between team members is extremely important as is also empowering and investing in more junior team members. I create and maintain documentation for systems either I\'ve implemented, those I\'m familiar with and those I\'m not.I strive to give customers the best possible experience whilst at the same time resolving their issues as efficiently as I can.
