What's the difference

My time is my value. So when you choosing me you can expect that job will be done in short terms and perfect. I not like to do something that not need be done, i prefer use developed components and solutions. That not mean i can't do development. I working with different programing tasks for last 26 years. yes, from 6 y.o. I live in it. So i prefer do something new&interesting; I can
handle all tasks from linux administration/virtualization upto end-user web
for voip. Only task i never do - grap…
