about me

Builder.
Admin.
Problem Solver.

My name is Nikolay, I develop websites, administer servers on Linux and many other interesting things. For more than 10 years I have been setting up Unix servers and developing websites of varying complexity.

I am fond of hacking and system security. I will be glad to become a part of your team or perform interesting tasks for you — write a website, a script, optimize a server, automate a task, write an application, or remove viruses.

I also play music and drink coffee. Books make me relax. Being able to both design and develop is a lot of fun.
