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

I started working with the computers because I was not satisfied with IT technology and I wanted to help others and myself.
I have been making customized solutions since 2009. I am programming in several programming languages. For each problem I always choose the most suitable language.
I am happy when my work helps somebody else and makes his work easier.
The development of software does not concern only making programs. At first it is necessary to understand the needs of a customer and the problem which is to be solved. Then the suggestion of the solution follows and then the exact specification must be done.

After implementation, it is necessary to maintain the servers where the implemented application runs.
I continuously propose and implement other ways to make work process more effective and I write the documentation.

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

You can expect these advantages

I use both my theoretical knowledge which I got at my studies of information at the Technical University in Prague (ČVUT) as well as 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.

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

Lectures

I regularly attend conferences not only as a listener but also as a lecturer:

BTRFS filesystem and backup at conference OpenCamp Bratislava 2019
Workshop Video editing in Linux using SW Kdenlive at a conference InstallFest 2019 .
I lectured about moder file system BTRFS at the LinuxDays 2018 conference and OpenAlt 2018 conference
OpenAlt 2017 coreference and my lecture "Backup by turning on my computer".
On OpenAlt conference I had lecture single board computer Banana Pi R1.
Arduino Day 2016 in Prague.
Educational Lectures at high schools.

Personal achievements:

In 2013, I completed 526 hours of sports training and 350 of them were cycling. At the weekend I had two MTB ½ marathons and I myself provide support and service. And all this while a I was an employee.
The climbing stream detection project for racing airplane modelers has helped win a medal place several times.
In my spare time, I have fully assured the cooperation of the company and the sports team with the design and realization of the sponsored items.
During the two flu I learned to solved a Rubik's cube and in two summer I learned to swim kraul well.
