I am a good old-fashioned IT expert who brings the IT base of companies from the dark ages into the 21st century. I have a university degree in IT from the prestigious Czech Technical University in Prague, have worked on dozens of demanding IT projects, have published countless expert articles, yet I still believe in the importance of hands-on experience and tinkering with the technologies I work with.

As a Linux server admin, IT consultant and software developer well-versed in Java, Bash, PHP, Python, SQL and other programming languages or technologies, I can help you to solve complex problems that are far beyond the scope of individual specialists. These are the main areas I can help you with:

  • Linux server installation and management — web servers, mail servers, application servers, special-purpose servers, etc.
  • Ransomware-proof data backup and recovery — providing a backup service or complete backup implementation to protect your data from ransomware
  • Server applications management — mail servers, web applications, open-source solutions and CMS, e-commerce platforms, team collaboration apps, monitoring, web hosting systems, virtualization, etc.
  • Custom software (and hardware) development — I have mastered dozens of programming languages and technologies that can be combined to solve new problems. Besides developing common web applications, I’ve been working with IoT devices and embedded systems for years and have published several series of articles about it.
  • IT consultancy and analysis — selecting the ideal software or hardware for your company, an analysis of company business processes, IT security audits and risk assessment, etc.

If you need to bring your company’s IT up to speed, or have some atypical IT assignment, I would be delighted to discuss possible solutions and our potential collaboration.

Technologies I work with

  • programming languages — Java, Bash, SQL, PHP (Nette, Symfony, Composer), Python
  • software release and source code maintenance — Git, GitLab, unit testing
  • administration of Linux servers — Debian, Ansible, RAID, Apache, ISPConfig, postfix, dovecot, MySQL, PostgreSQL, named, LTSP, samba, asterisk, openvpn, openfire, ssh, virtualization (VMWare, Proxmox, Qemu/KVM), Docker, NodeJS, etc.; troubleshooting, encryption, network and application security
  • ARM single-board PC — Raspberry Pi, Banana Pi R1
  • networking — Ethernet, WiFi, TCP/IP
  • REST API connections and other technologies (embedded Linux, Yocto Project, LaTeX…)
  • agile development with methodologies such as SCRUM

Firsthand recommendations

During the breakdown of our Linux server we turned to Mr. Jebavý with the request for help. Because the breakdown was at the worst time possible, right in the middle of the season and, what is more, at the weekend, the help was urgently needed. Mr. Jebavý answered our call for help immediately with his offer and on Sunday morning the fault on the server was fixed. I can recommend Mr. Jebavý for his speedy and efficient work.

Our firm Sievert Consulting s.r.o. has a long-term partnership with Mr. Jebavý, who looks after the administration and maintenance of all hardware parts of our application which serves for the administration and maintenance of the property SW KLID. We can only recommend the cooperation with Mr. Jebavý to those who want to have stress-free business and want to concentrate on their business without loosing time with server administrators. We look forward to many other years of cooperation.

In establishing my public notary office I needed to solve the problem of building up a small computer network with a small server, data sharing, distant access to data and their security and storing. The cooperation with Josef Jebavy was professional, fast and practical. Everything works and is still working according my expectations. Josef designed the server according to my needs — he installed a smart device having small consumption including the data storing at the second small device. I can only recommend him.
