Bc. Josef Jebavý: IT consultant, Linux, software development, DevOps, IoT

I am involved in many different things, whether at work, at home or in my leisure time. I make my living from computer science.

Education

After graduating from high school, where I was a successful competitor in mathematics and physics Olympiads, I graduated from CTU FEE in computer engineering, where I gained theoretical knowledge of electronics, programming, computer hardware and computer science in general.

Skills and experience

I am involved in server administration and in the development of custom software projects, also in combination with electronics.
I program in languages such as Java, Python, PHP, SQL and I script in Bash. I'm happy to use C++ where necessary. I also like SQLite, XML, JUnit and DBUS, for example.
I map data into OpenStreetMap and I also use these maps in various formats in different projects and devices.
I am no stranger to networks, whether wired or wireless, nor to network protocols or computer hardware.
I have no problem connecting low-level tasks with high-level ones, for example soldering the hardware, programming a microcontroller in C and then connecting the device to a PC, where everything is processed by a Java program. I really enjoy big projects like this with a complex architecture.

I develop custom projects for wireless data collection. These are complex projects involving the design and manufacture of hardware that is then interfaced with a PC/server where the collected data is processed and displayed.
I install GNU/Linux on desktops or servers.
I deploy RaspberryPI as an embedded PC.
I deploy ready-made opensource solutions to customers and then maintain and modify them, for example the Prestashop e-shop. However, I do not do graphic design.
For peace of mind and sanity, I only use GNU/Linux. I do not deal with Windows installations, nor with issues and technologies exclusive to Windows.
I develop electronic devices.
Thanks to my broad skills, I can comprehensively develop projects that combine electronics, hardware, software and state-of-the-art technology.

Service offerings

Here is my professional services website.
And here is an offer of specific typical packages related to Linux installation and server management.
To keep your data safe, I have developed a unique backup solution that will protect your data even from ransomware.

Free Time

I'm no stranger to sports, plus it's a must for a programmer! I take a holistic view of sport, which is why I do a variety of sports: cycling, weight training, swimming. I'm also interested in sport from a professional angle, so I educate myself in this field and read specialist sports literature. Thanks to theoretical knowledge and experience from racing practice, I know how to train properly, how to eat and how to recover. I prefer to regenerate in the sauna.

I've recently taken up swimming and freediving, and when I'm by the ocean, bodyboarding.

Optimal performance also includes a good lifestyle: rest, fun, diet, etc. That's why I often cook delicious meals that provide energy for my muscles and brain. I have published the modified recipes I cook as a PDF cookbook.

For years I was a successful aeromodeller. I have built many aircraft, for example the three-metre Monarch glider. I have also built modified aircraft and aircraft of my own design, for example the Jeseter aircraft.

I used to be into railway modelling. I have a layout and a train set in TT scale.

In grade school and high school, I went fishing in the spring and summer. I used to ride my bike to go fishing and I took a liking to float fishing. I became very good at this method and even made my own floats.

Thanks to my excellent manual dexterity and technical skill, I was gluing intricate paper models even as a young boy. For example, a mechanically functional paper model of the Tatra 815.

I am involved in aquaristics. I grow aquarium plants and keep aquarium fish. And I have successfully propagated plants and fish. I have successfully bred labyrinth fish – the golden gourami.

I grow flowers, mainly palms and cacti. I am also reasonably ecologically oriented. I don't drink hard alcohol and I don't smoke.

Music

My favourite Czech bands are:
Kabat, Alkehol, Arakain
Foreign:
Korn
and my favorite singer is:
Daniel Landa

On other sites

I actively participate in discussions on web portals, where I help answer questions from beginners. I write articles for these web portals, mostly for root.cz. I have also published in print periodicals, most often in the magazine Praktická elektronika – Amatérské radio. More information about my professional publishing.
