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.
Software development is not just about programming. At first it is necessary to understand the needs of a customer and the problem which is to be solved. Subsequently, it is necessary to design a solution and create an exact assignment.
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 my theoretical knowledge, which I got at my studies of information at the 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.
After handing over all the information and documents, I work independently, so you will save your time when you would otherwise have to manage employees. I am able to quickly familiarize with the source code of a third-party application and, thanks to this, I bring value immediately after starting the collaboration.
Writing documentation is standard for me. The project, who to live, needs maintenance and without documentation, the later implementation of the requirements is very hard.
I care of security and deal with it preventively. I protect customer data as well as my own. For example, my laptop has an encrypted disk. As soon as a security issue arises, I respond proactively.

Lectures
I regularly attend conferences not only as a listener but also as a lector. Educational Lectures at high schools. List of planned and completed conferences.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 (socks with team logo).
- During the two flu I learned to solved a Rubik's cube. In two summer I learned to swim kraul well .
- I learned to play the piano myself.
