    Linux administrator/support technician | cPanel certified

    Croatia - Last active: 1 day ago - Tests: 6

    My main field of work is linux administration and user support in the webhosting environment. There's a lot of control panels I work with in this field but most common are whm/cPanel, whmcs, Plesk, virtualmin. If needed, I can learn to use any other control panel quite fast. From the operating systems, I have worked with a lot of gnu/linux flavors. e.g. centos, debian, ubuntu, cloudlinux ... My work can be divided to: 1. Setup of various services ( like above control panels, custom setups with nginx, varnish etc) 2. Troubleshooting various user problems ( e-mail problems, hacked web servers and web pages) 3. Migration of web sites from one host to another, using same or different control panels. 4. Optimization and security hardening of already setup servers. If you think that I can help you, feel free to contact me and I will be happy to have a look through your problem/proposal and let you know if I can help you out. To verify my cPanel certification please visit http://university.cpanel.net/c-summary.php?code=kcgx-913946
