Hi Sir, I'm a Professional Linux Server Administrator which is confirmed in my skills. I have 8 years of experience as Hosting Administrator in Poland. I know Linuxes, services,protocols perfect, due to my 8-years work I have high troubleshooting with finding reasons of any potential problems. I know perfect www (Apache, Nginx), mail severs (Postfix, Exim, Zimbra), and others. Antyspam mechanisms, security and different backups. In my work we had few times with high loaded www servers and we tuned them or loadbalanced so I have experience in tunning work. Professional and honest work with patient contact - thats me. Kind regards.
