I move the IT technology base of companies from prehistory to the top of the market

If you need to solve IT problem or get some advice do not hesitate to contact me.

You can expect these advantages

I use my theoretical knowledge, which I got at my studies of information at the Technical University in Prague (ČVUT), and my practical experience. I always go to the heart of each problem and try to understand problems around me.

I have individual approach to each customer and I suggest the solutions and development which lead to the best result.

The software which I recommend I know well as a programmer and also as a user and therefore I am able to offer practical and complex advice. For example, I run Linux on my desktop too. On my client servers I run the same programs as my servers. Therefore I am able to explain in detail its functioning, point out possible problems and difficulties and suggest how to avoid them.

I prefer continuous personal consultations but at present I often use electronic communication, e.g. e-mail, chat (jabber), telephone or VoIP and video calls.

Writing documentation is standard for me. The project, who to live, needs maintenance and solution of requirements is very hard work, without documentation.
