Samuel Uhliar

How can a young person get involved in interesting projects and companies already in High School?

My name is Samuel, and I’ve been fascinated by technology since childhood. I started programming at the age of six, trying to understand how the games I played actually worked. That curiosity gradually led me to building my own projects—such as the mobile game Space World, which I created at a very young age.

Today, I focus mainly on building technology projects at the intersection of fintech, product development, and entrepreneurship. I’m interested in how technology can simplify complex systems—such as investing, financial services, or education. In addition to development, I also analyze new projects and work on building startups.

At CODECON, I’d like to bring a practical perspective of a young builder—someone who doesn’t see technology as just code, but as a tool for creating new products and companies. I believe my journey—from a child programmer, through building my own projects, to launching startups—can inspire developers who want to turn their technical skills into real products and businesses.

Patrik Plachý

Trustworthy AI in practice: How to build a secure LLM architecture for LLMs

I started as a developer working with C, later moving on to C++, Pascal, and Python. I then worked on developing modules for Oracle Database and transitioned into backend development and design. I helped customers design and implement enterprise systems.

In recent years, I’ve focused on Linux, clusterware, and high availability. I’m currently a Senior Solution Architect at Red Hat, where I specialize in container operations and deploying them for customers in the Czech Republic and Slovakia.

My passion for LLMs and scaling applications goes hand in hand with my belief that knowledge gains value when shared. Within the team, I act as a mentor and a filter for tech trends. When I’m not optimizing code, you’ll find me in the Danube—the cold water is my best way to debug my mind.

Jakub Rapant

How Developers Actually Grow (and How Not to Get Stuck)

Hi, my motivation to become a speaker at this year’s Codecon actually came from the last one in Bratislava. I was part of the RPC team in the expo zone, where I had the chance to have great conversations with a large number of attendees who stopped by our booth. It was a really diverse mix of roles, seniority levels, and personalities.

What stood out, though, was that many of them showed a certain sense of being “lost” when it came to where and how to move forward in their careers. This kept coming up across both juniors and seniors, and that’s when I thought it would be valuable to bring a self-leadership talk to the stage—one that, without unnecessary HR fluff, shares what has worked for me in my career and what could, ideally, help others find their direction.

Another reason is probably that I genuinely enjoy speaking—especially knowing that it might inspire someone along the way 😊

Peter Miľovčík
