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.

Matej Švec

Rendering millions of records: From architecture to visual testing

Phil Royston

Cross-Dysfunctional Teams: Where The Magic Stops

Having wandered reluctantly into IT about 30 years ago, my first contact with formal testing came unexpectedly in 2002, when I was made the Test Manager on a project. It was then that I felt that I had found my true calling.

I became the go-to person they called when there was a “problem in testing”. But after a few years of fire-fighting troubled projects, I began to wonder if there wasn’t a better way. This first led me first to start a testing company 11 years ago and eventually sparked my current fascination with quality engineering and self-organization.

AI Agents and the Future of Testing

👋 I’m Marcel Veselka, founder of Wopee.io, with 20 years of experience in testing. I see testing not as a brake on innovation, but as its safeguard.

Today, AI accelerates everything — development, deployment, and unfortunately, the errors that come with them. That makes testing more important than ever.

AI agents are fundamentally transforming testing. They eliminate monotonous tasks, speed up processes, simplify complexity, and free up time for what really matters: thinking, creating, and improving software quality. Testing is evolving from routine, sometimes tedious work into a process that brings joy, value, and confidence that everything works as it should.

I studied in Žilina, and CODECON gives me a great opportunity to engage locally and support and motivate the community at home. 🚀

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 😊

What People Are Saying About Us

It was a great experience for me. I’m especially excited about people’s reactions. I spoke with various people, and they were all very happy that something like this had been organized. They praised the format, content, organization, and overall atmosphere.

Thank you for an excellently organized event. This was my fourth time participating, and it seems to get better every year. I’m already looking forward to the next one!

It was amazing, intense, and perfectly organized. Bravo!

The CODECON program was truly packed. The diversity of lectures and workshops covered a wide range of IT trends. It was clear that the organizers put great care into selecting the speakers, as the lineup was truly top-notch. I truly appreciate having another event that helps our community grow and move forward.

CODECON in Slovakia is exactly what the Slovak developer community has long needed. Having a space where developers can meet, share experiences, and connect is truly invaluable. I’m delighted that we have an event that supports inspiring ideas, innovative projects, and talented people.

Thank you for an excellent conference. The event was top-notch, and I enjoyed it both as a speaker and a participant. I especially want to highlight the stage managers’ willingness and proactivity during the rehearsal and in making last-minute adjustments to the presentation.

First of all, thank you! One of the best parts of the conference was reconnecting with former colleagues and having the chance to catch up. I don’t mean that as criticism of the program at all — quite the opposite. It’s one of the greatest strengths of the event.
