I specialize in advancing the IT infrastructure of companies, transforming outdated systems into cutting-edge, market-leading technology solutions
My journey in IT began with a desire to improve the existing technologies and to create better, more efficient systems for both personal and professional use. Since 2009, I have been crafting custom solutions, leveraging my expertise in various programming languages. For every challenge, I carefully select the most appropriate language to ensure optimal performance and efficiency. I find fulfillment in developing software that not only addresses the needs of others but also makes their work processes smoother and more productive. To me, software development goes beyond programing. It starts with a deep understanding of the client’s needs and the specific problem that needs to be solved. Once the requirements are clear, I design a tailored solution and create a precise project scope. After implementation, I ensure the seamless operation and maintenance of the servers supporting the application. I am always looking for innovative ways to enhance workflows, and I take pride in providing thorough documentation to support long-term system success.
If you need to solve IT problem or get some advice do not hesitate to contact me.
If you need to program an application in the PHP framework Nette or Symfony, that runs on your own server, then you are my typical customer.
You can expect these advantages
I combine the theoretical foundation gained from my studies in Information Technology at ČVUT with extensive practical experience. I approach each challenge with a focus on uncovering its core issues, ensuring that I fully understand the problems at hand.
I take a personalized approach with each client, tailoring solutions and development strategies to achieve the best possible results.
The software I recommend is not only something I know well as a programmer, but also as a user. This dual perspective allows me to offer practical, well-rounded advice. For example, I use Linux on my personal desktop and run the same applications on my client servers. This hands-on experience enables me to provide detailed explanations of system functions, identify potential issues, and offer proactive solutions to mitigate them.
While I value direct, ongoing consultations, I am also accustomed to using electronic communication methods such as email, chat (WhatsApp), phone calls, VoIP, and video conferencing for effective and efficient collaboration.
Once I’ve gathered all necessary information and documentation, I work autonomously, saving you time and reducing the need for additional management. I am able to quickly familiarize myself with third-party source code, which allows me to add value immediately upon starting a project.
Writing thorough documentation is a standard part of my process. I believe that a project needs proper maintenance, and documentation is essential for the successful future implementation of any changes or requirements.
I prioritize security and approach it with a proactive mindset, ensuring that both customer and personal data are protected. For instance, I encrypt the disk on my laptop, and I address any security concerns promptly to mitigate potential risks.
If you're interested in collaborating, I can walk you through the process and outline how we can best work together to meet your objectives.

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:
- To optimize my finances, I started renting rooms in Prague for short-term stays. For this purpose, I prepared the apartment, study law/bureaucracy, learned how to use platforms like Airbnb and Booking. For this tasks a made process and than delegated it. This allowed me to leave for the entire winter while everything continued to run smoothly.
- 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 very well .
- I learned to play the piano myself.
