CEO of ELOS Technologies, with more than 20 years of Open Source and thousands of miles of nautical experience, starting with Linux in the early days of Slackware. I navigate a team of talented and dedicated professionals through the ever-changing information technology market while helping them to maintain their carrier satisfaction and work/life balance. Focusing on the organizational and relational aspect of technological innovation, I favor interdisciplinary view of change and progress in IT. When skippering our vessel through various weather and maritime conditions, I always choose the route that is the safest for my crew and the most enriching for our passangers.
Štěpán is the Sales and Marketing Head at ELOS Technologies and loves helping companies with their subscriptions, professional services, and certified training. He has spent the majority of his career in the IT sales industry, gaining experience through Red Hat Training when he worked as a Sales or a Delivery Manager and through subscription advisory. While managing a team of sales professionals in his day job, Štěpán also works as a solo pianist in star-rated hotels and restaurants and successfully manages a professional event band. When on the boat, he's often seen next to the mast being heavily slapped by various types of sails, ropes, and other parts of the rigging. This guy really needs to feel it all!
Daniel Kubenka has boarded our ship early 2018. He is a go-to person for anyone with questions regarding subscriptions from Red Hat, Zimbra, EnterpriseDB, CloudBees and many others. He is also responsible for maintaining a partnership with our sea gods - software vendors. Well, you don't want to mess around in this area, right? When under sails, Daniel is handling our Marine VHF. Making sure he catches every message that is related to our yacht. When onshore, he enjoys sports activities such as fishing, tennis, and skiing. His dream is actually to make money from fishing one day, because "Work is for people who don't know how to fish", as he often says.
Zuzana is an indispensable part of our crew, ensuring everything runs smoothly – from supporting the sales and technical teams to handling finances and overseeing the daily operations of the office. She is responsible for issuing and processing invoices, keeping a close eye on the financial side of projects, and making sure that all administrative aspects of yachting – contracts, agreements, and documentation – are always in perfect order.On board, she is the backbone of our operations, keeping the budget in check and ensuring everything aligns with our financial plans. Even when things get tough, she always maintains control and keeps everything organized.Off the boat, she enjoys capturing moments through the lens of her mobile phone – because, after all, budget is budget!
Andrea has been sailing with ELOS since 2017. In the past, you could have met her in contact with our clients regarding training and back-office management. After a short maternity "leave", although with one foot still on board our vessel, she added to the existing function the care of online marketing activities. Just like in the office, regular refreshments are also important on the ship, especially in the form of "gin soup", which she can cook perfectly and repeatedly so that the crew has enough strength for the next sailing. During races, she can hold the publication device in one hand and the gennaker rope in the other and is not afraid to use both. She devotes her free moments on land to quality books, traveling and her family.
Jan has been working in the IT industry since 2009, gaining experience mainly in network and system administration. As a Senior Systems Engineer, he is now focused on automation and container technologies, helping our customers with their transformation projects. In addition, he is also a Red Hat Certified Instructor, always enthusiastic to pass his knowledge to others. Outside the office, Jan enjoys nature trips with his dog. When on the boat, you can often see him behind the helm or trimming the mainsail.
Having 20 years of experience working on various IT infrastructures, with a background in open-source, Puppet, and infrastructure automation - Honza is considered the father of our monitoring stack. He brought this baby up and turned it into a successful independent individual. Outside of work, Honza enjoys rock climbing and can also be found taking long bike rides through the hilly countryside. As a member of the crew, he has one of the toughest jobs you can imagine. His bowman's duties include e.g. climbing the mast, operating the spinnaker pole, or changing the headsail. This dude doesn't take no for an answer.
It will soon be 30 years since I booted my first Linux kernel. Ever since I have been using Linux and other open-source projects both for work and fun. The only exception being the language localization of the Palm OS operating system to many central European languages. I really enjoyed reverse engineering and hacking the Palm OS since it goes well with my creative nature. I like to dive into the details of various software and hardware gizmos. Although I hadn't planned it I followed a generation-long family tradition and became a teacher or instructor as it is called now. I really enjoy meeting people in training. My recent activities revolve around OpenShift administration and development. All the IT courses take place indoors. In order to compensate for that, I joined the Czech branch of Outward Bound International. In our outdoor courses, we encourage people to learn and grow through experience. When it comes to maritime endeavors I am able to support our team with my diving skills.
Vratislav is the young brain on our team. Linux enthusiast, who loves the origins and story behind GNU/Linux and the free software movement. He started experimenting with GNU/Linux when he was just 13 years old. Vratislav enjoys solving technical challenges with both old and new FOSS tools. His favorite waters are those around Antarctica, the habitat of our beloved Linux penguins. Recently, he has shifted his focus on container vessels and has already enjoyed a couple of moments of being solo behind the Helm. Expect to hear a lot more about this mariner in the future.
Petr is practically a veteran in ELOS. His existence here dates back to the days when punched labels were already leaving their limelight and tape libraries were still a futuristic hype. At ELOS, he focuses on everything from Red Hat Linux, Red Hat Satellite, Red Hat Ansible Automation all the way to the Red Hat OpenShift Container Platform. In regards to his innate didactic skills, he is also a certified Red Hat instructor. In his free time, he likes to go to nature, ride a bike or a scooter and try to stay out of reach of zeros and ones. He has experience with yachting outside of the ELOS Sailing Team and is therefore very valid support for our crew. Behind the helm, his hand is confident and sober, like the look of an Indian chief at dawn, and he trims sails with Helvetic precision.
He steered his course from electrical engineering to DevOps, specializing in infrastructure automation and GitOps practices. With a strong technical foundation, he navigates the challenges of container orchestration and system reliability.Off the main route, he explores new technologies and optimizes operations. What started as a small Kubernetes cluster on a Raspberry Pi has grown into a robust five-node fleet with virtualization, high availability (HA), and a focus on energy efficiency.When covering longer distances, he lets the servers run and jumps on his bike. Cycling helps him clear his mind and come up with new technological experiments.
In 2020, he set course for automation and process simplification, eventually steering from a developer’s role into DevOps. With a strong programming background, he focuses on building robust solutions and writing clean, readable code. If he has to do something twice, he’d rather write a script for it.His true fascination lies in database and authentication services, which he explores both as an administrator and a user. Every day, he scours GitHub in search of new tools to test on his local cluster.As a skilled swimmer, he moves just as confidently through the sea of platform solutions, constantly seeking ways to fine-tune performance, automation, and reliability.

Most often, he can be found working on IT transformation, FinOps, and technology management—areas where IT efficiency directly impacts business success.In his free time, he sticks to old-school pleasures—reading paper books, listening to music, and pondering philosophical dilemmas. Like whether to call it a night and finish that damn YouTube tutorial tomorrow or pour another drink and face it like a man… well, more like sit down to it like one.
For nearly 20 years, Lukáš has been sailing the waters of enterprise software delivery and his current duty is to be the evangelist for Cloud & Middleware technologies and DevOps movement. Aboard, he mostly observes Clouds and trims the headsail, so our vessel can quickly tack to correct solution. He is also a diver, so he is obliged to scrape barnacles from the hull and the keel, but he also likes to submerge into the depths of our passengers' troubles and helps them to consult any possibilities and ways of implementing modern cloud technologies into their software projects. Beside consulting, implementing, preaching and sailing he is also a Red Hat products instructor.
After more than 20 years of sailing on an ocean liner, Jaroslav decided to enjoy his ride on a sports sail yacht with the wind in his back and slightly gray hair. Historically, he has focussed on everything in IT from application development to SharePoint infrastructure, for customers in the areas of finance, e-commerce and automotive. Recently, he has been dealing mainly with the Kubernetes / OpenShift platform, including DevOps / GitOps processes, both on OnPremise and in cloud environments. In his free time, he devotes himself to his family and the endless reconstruction of an old homestead. With regard to our manual dexterity, we are not afraid to entrust him with any repair or modification of our sailboat. Whether it's an action in the engine room or a repair of the fuselage delamination. Seeing him with an eccentric grinder is an experience that will be etched in your memory for life.
