SAVE THE DATE! CODECON #Žilina

My journey into IT hasn’t been straightforward. Programming didn’t come naturally to me for a long time, and throughout both high school and university, I often wondered whether I had chosen the right path. Then things started to change…

I’ve been working at GLOBESY for over two years, where I’m now building an AI Ops architecture that takes routine operational tasks off the development team’s plate. This is also the focus of my master’s thesis in Intelligent Information Systems at the University of Žilina.

I’ve built and deployed apps using Flutter and Spring Boot in production, but these days, my focus is more on DevOps.

Before getting into IT, I spent over five years leading people in youth organizations and organized more than 20 sports and gaming tournaments. Those experiences taught me how to communicate clearly and connect with people on a human level.

Alongside my work, I’m also studying theology in Vienna, with a focus on leadership.

And, of course, I’m always happy to enjoy a cup of good specialty coffee in great company. ;)

I love the intersection of technology, business, and marketing. I have over 20 years of experience in IT and cloud computing, helping mid-sized and large enterprises design and operate solutions across infrastructure, containerisation, scalability, and security.

I’ve spent over 10 years in B2B, working in product management and marketing, as well as building and leading international technology and sales teams. I regularly speak at conferences, deliver training on cloud-native technologies and Kubernetes, and advise companies on productisation, leadership, and business strategy.

I’ve been working in software for over 13 years. Before that, I studied IT and philosophy.

I’ve been pretty lucky throughout my career. I joined a growing startup where I learned pretty much everything I know. Nine years later, I’m still here and still enjoying it, even though we’ve since become part of a large corporation.

For the past few years, I’ve been leading a team with a high degree of autonomy, which gives us plenty of room to experiment with how we build software. Over time, we’ve iterated on the way we work and arrived at what I believe is our best setup so far. That’s what I’d like to share with you.

I believe software development is a team sport, not an individual activity. We get the best results when everyone feels like they’re part of the team, has a sense of ownership, and can take responsibility for the things they work on. When people feel like they’re working on something that’s truly “theirs” and have a real say in the decisions, the whole team benefits.

Outside of work, I founded an IT community in Poprad and now run one in Trenčín (a.k.a. the Slovak digital nomad 😉). I also have four young kids and volunteer with people experiencing homelessness.

Across all these areas, I keep coming back to the same lesson: if we want to make things better, we need to build on trust, not control.

I sit at the intersection of customer data, feedback, adoption metrics and churn analyses. I see where the gap forms between what the team builds and what customers perceive as value. I’m passionate about customer success because I believe in a fair exchange of investment-to-value. At CODECON, I want to bring a perspective developers don’t often see: what customers truly need, what frustrates them, and why some leave even when the product works technically very well.

I'm an introvert who moved to the Orava region. After a while, I started finding it a little lonely working as a programmer on my own, so for the past 15 years I've been finding different ways to support the Slovak developer community.

I started out writing for vyvojari.sk, later I learned about Daniel Harcek's WebUP, and eventually I launched the vyvojari.dev community project. To help it, I started writing a weekly newsletter at https://blog.vyvojari.dev/tag/tyzdennik/. Through WebUP, I also got involved with CODECON and ended up on the program committee. A year ago, I became a co-host of Dávid Tvrdoň's Link podcast.

None of this was planned. All it ever took was reaching out and taking the first step. And that's exactly what I want to talk about: at a time when AI is taking over an ever-growing part of our work, we're losing what used to make us happy — programming — and somehow we have to deal with that. Being visible in the community may be the cheapest insurance we can buy.

I don't have a theory or a methodology, but I have fifteen years of trial and error, and a few things that worked. I want to share those with you.

I’m the CEO of the fashion brand Dajana Rodriguez and the founder of Promedea, where we teach people and businesses how to work with AI.

Over the past few months, I’ve gone all-in on AI and vibe coding in my own company—not as something to talk about in presentations, but as a tool that delivers real business results. I’ve built several internal applications, developed our own AI system that connects the entire company, and automated key business processes.

More than 800 people have attended Promedea workshops. I keep things direct and practical, with no unnecessary theory. I show real-world implementations that can have an immediate impact on the business.

My motto: “No fluff. No BS. Just practical, real-world application.”

I lead Data and AI at Ringier Slovakia, where my team and I build production AI systems for newsrooms as well as internal tools. I also write code daily on my own projects. Repeated patterns in code reviews led me to explore how to turn insights from reviews into rules that work for both people and AI agents.

My name is Andrej Hlúbik, and I am one of the creators of the BuildITBreakIT workshop. The other creator is my wife 🙂.

I am an ethical hacker (penetration tester) at Siemens Healthineers, where I specialize in testing internal systems and medical devices. I also enjoy giving talks at various events for students and teachers, because the younger generation is our future.

In my free time, I enjoy experimenting with local AI models.

I’m a Developer Relations Engineer at Qodo, helping teams build high-quality software and navigate the AI era. My blog has been read over 2 million times, and thousands of developers and testers have taken my courses. I speak at conferences around the world and I am a Codex Ambassador and AAIF Ambassador. I live in Slovakia with my wife and our four children.

I've been working as a software developer for over 10 years. Every year, I enjoy it more, and every year, I realize how much I still have to learn. I mainly write about Angular on Medium, but lately, I've been getting interested in pretty much everything, including backend development.

I'm a software developer with a background in biomedical engineering and bioinformatics. I work on medical mobile apps and explore practical ways to use AI in software — from helping with the development process to integrating generative AI directly into applications.

I’ve been working as a programmer for over 16 years, currently as a full-stack developer specializing in Java, Spring, and Vue.js. I’ve worked on a variety of projects across transportation, government, banking, and telecommunications. Since 2019, I’ve been working 100% remotely as a freelancer and have traveled around half the world as a digital nomad.

I’m the CTO and co-owner of Muziker. I started out as a software engineer (FIIT STU), and together with my team, we built a large part of our e-commerce and ERP architecture in Ruby on Rails.

Today: 50 countries, 45 domains, 50+ million requests a day, and a ClickHouse DWH. I’m leading the AI transformation: custom-built agents, custom MCP servers, production RAG, agents for SEO and GEO, and other automation solutions.

I’m on the board of Ecommerce Slovakia, and Muziker supports RubyAkadémia.

I have 10 years of experience in software development, progressing from a junior developer through mid-level and senior roles to becoming a solution architect in the payments domain at Slovenská sporiteľňa.

For the past year and a half, I’ve also been leading a team of nine people: four developers, four business analysts, and one solution architect.

I spend around 60% of my time on leadership, while the rest is dedicated to my work as a solution architect. I design technical solutions, advise developers and analysts, take part in production on-call rotations, and keep an eye on industry trends and competitors in the payments space. This helps me identify opportunities and shape the team’s future direction.

I'm a seasoned software developer and IT consultant with extensive experience designing and delivering information systems. More recently, I've been focusing on the practical use of AI and local language models: integrating them into development workflows and deploying them in client solutions.

I’m a host, facilitator, and public speaking trainer. I help people communicate with greater confidence, clarity, and impact — without the unnecessary fluff.

I’ve already hosted a workshop called *Debug Your Delivery* at CODECON Bratislava, and I’d love to build on that experience with another hands-on talk in Žilina.

I’m passionate about bridging the worlds of technology and communication, and showing people that even the best idea needs great delivery to truly resonate with its audience.

I stumbled into software testing by chance and never looked back. Over the years, I’ve specialised in test automation architecture. These days, I’m increasingly focused on AI skills that can build and maintain test frameworks across different projects.

I’m naturally curious about new technologies, but what matters to me even more is whether they fit into a well-thought-out process that actually works.

I currently work as an AI & Automation Engineer at Multitude, with many years of experience in software engineering.

I’m also starting to give talks on various IT topics. I enjoy talking about subjects I find interesting, sharing my knowledge and insights with others, and learning along the way.

When I’m not behind a computer, I enjoy climbing, both indoors and outdoors, making music, and, above all, spending time with my family.

I’ve been building things for the web for almost twenty years, and for the past ten, I’ve been using Elixir in production every day. I was CTO of an NBS-licensed payment provider, and today I work as a senior engineer on a large-scale Phoenix application running in production for a US client. For the past two years, we’ve been using AI extensively—not as an experiment, but as part of our everyday workflow and as a component of our product. This has given me real-world data to share, rather than relying on studies found online.

Alongside my day job, I build open-source tools to support my own workflow and share them with the community: [phxagents.dev](http://phxagents.dev/) (a harness for AI agents in Elixir), [prmarmot.dev](http://prmarmot.dev/) (pull request triage), [getscribe.dev](http://getscribe.dev/) (a knowledge base maintained by an LLM), and cmux-sentinel (an overview of running agents in cmux). AppSignal has published a case study about my CLI agent skill.

I’ve spoken at CodeCon three times: in Bratislava, where I talked about Phoenix LiveView; in Žilina in 2024, where I covered search in PostgreSQL; and in 2025, when I spoke about context engineering. The last two talks are available on YouTube. This year, I don’t want to add to the AI hype. Instead, I want to share concrete techniques and production metrics that developers can apply in their own work.
