A Growing Partnership: Royal FloraHolland Visits Levi9 in Novi Sad 

This month, we had the pleasure of welcoming our partners from Royal FloraHolland, the largest international floriculture marketplace for flowers and plants, to the Levi9 office in Novi Sad. The visit provided an excellent opportunity for focused collaboration, as well as for further strengthening the partnership we have been building since the very beginning of our cooperation. 

About the Levi9 & Royal FloraHolland Collaboration

Levi9 has been collaborating with Royal FloraHolland since 2024. The partnership began with the migration of existing services and has since evolved to include the modernization of existing solutions as well as the development of new logistics-related functionalities. 

 

Over this period, the Levi9 team supporting Royal FloraHolland has tripled in size, driven by consistent delivery, high-quality results, and dedication that exceeds expectations. Our partners particularly value our strong focus on understanding complex systems and proactively proposing effective solutions. 

Strengthening the Partnership

The primary purpose of this visit was operational, with teams working closely together to prepare for the PI Event in the Netherlands. This event marks an important planning moment, bringing teams together to align on priorities, delivery goals, and upcoming work. In a positive and productive working atmosphere, Levi9 and Royal FloraHolland teams aligned plans, exchanged insights, and jointly worked on planning and estimations for the upcoming PI.

 

This hands-on approach allows us to stay aligned, openly address challenges, and make shared decisions that contribute to delivery quality and long-term solution stability. 

 

We were especially pleased to meet Rogier Herrebout, the new Logistics Director at Royal FloraHolland, who had the opportunity to meet with Predrag Kapamadžin, Delivery Director at Levi9. From the very first meeting, we established open, direct, and pleasant communication, laying a strong foundation for continued collaboration. 

After Work Hours

After the working sessions, we continued the visit in a more relaxed setting, enjoying bowling, dinner, and informal conversations together. These moments provided another opportunity to get to know each other better, strengthen personal connections, and continue building relationships that are both professional and friendly.

***

Since the start of our collaboration, we have been conducting two mutual visits each quarter – one in Serbia and one in the Netherlands, enabling us to build close relationships on both a professional and individual level. 

 

We look forward to continuing this successful collaboration and to many more shared milestones ahead.

Hope is not a Strategy

Companies, nowadays, establish good decision-making competency as a company value. Good decision-making skills get assessed in almost every software engineering hiring or performance review process. This, not so highly available commodity among representatives of any profession, software engineers included, is at core of success at any level in the organization and success of the company itself.   

The rate of changes in business environments, the level of demand for “stuff that works” and its complexity is constantly increasing. Increased pressure on solution providers in the Software and Data Science engineering domains results in a privileged status of these engineers in demand. It’s another confirmation of the common wisdom that ” Knowledge is power”. The capacity to learn and apply new grasped knowledge is already the most wanted currency in the industry.  

In the hour of need, everyone relies on leaders to lead toward astounding triumphs. The solution provider heroes will be apprised and celebrated. Others will fade into oblivion and eventually extinction. Automation and Artificial Intelligence at scale, the common solution ingredients today, are raising the bar for good decision competency.    

How to increase chances to stay in this privileged group of good decision makers in the future, how to grasp knowledge and how not to rely on hope predominantly, is in the essence of this talk.

How to break the police bodycams for fun and pizza?

The Dutch police has been trying to collaborate with ‘private partners’, including the Dutch hacker community in the Netherlands, for years now (the great Public Private Partnership or PPP), with mild success. So when they asked us what they could organize to get to know us, we replied with “invite us to hack police sh*t and eat pizza’s”. We thought we would never hear from them again. Surprise surprise, they eventually invited us in. So we created a team consisting of brilliant hard- and software hackers from the Dutch hacking community and went to the Amsterdam police station to try and hack some of their obsolete bodycams. Did we succeed? Come and find out and prepare to roll laughing on the floor! This talk is part of annual Levi9 Secure9 conference.

Multiple Ships to the Island – Micro Frontends & Island Architectures

In the last year, new frameworks have emerged or gained popularity, making use of the island architecture, a paradigm that aims to reduce the volume of JavaScript shipped through “islands” of interactivity that can be independently delivered on top of otherwise static HTML.

Many people started to confuse this pattern with micro frontends – which are all about scaling the development of a web application. Now, we have two patterns – one to scale the performance of a website and another one to scale the development. It turns out – they are not mutually exclusive.

In this talk, micro frontend expert Dr. Florian Rappl will introduce both architectural styles and show how they can be combined to create outstanding web experiences that scale not only in development but also in usage.

When nimble is not fast enough: Will AI and Data leverage your DevSecOps journey

In the modern Data and Tech world, you should either live under a rock or have someone cut off electricity in your apartment to avoid any significant interaction with AI. 

A great chance to gain the experience of DevSecOps and Data stories directly from the producers of a well-known and trusted DevSecOps platform with more than 30 million users. I firmly believe that a story can aid and inspire an audience to try to do extraordinary things in their data world. Thrilled to have a chance to reveal a few answers together with you: 

  • What is the effect of the beautiful friendship between Data and the DevSecOps platform? 
  • How does leveraging the data offer developers throttle in their daily work and keep them prevented from a headache and bad mood? 
  • What should put a smile on people’s faces – does anyone mention productivity? 
  • Is AI your best friend or your worst nightmare (or both) on the developer journey – the question is so pathetic, but the judgment will be more enjoyable, I pledge. 

Forget about hypes and buzzwords; let’s see AI in action making a developer’s life easier and super-efficient, with a small help of data, of course.

Software Is Details – KEYNOTE SPEECH

“It’s just a detail.” Have you ever said that or been told that? Whether it’s about implementation or requirements, we often use the word detail to suggest that something is not important enough to worry about.

There are so many things to worry about in software development that we need to prioritize — too much detail, and not enough focus. The problem is that within software, the details matter because that’s what software is: lots of details brought together in combination. If we don’t focus on the details, we get debt, defects, and delay.

Thinking Serverless in your Architecture

Serverless applications are becoming a popular architectural pattern for development teams from startups to large enterprises. These architectures provide agility, reliability, and scalability that is difficult to find elsewhere. But building serverless applications requires new architectural patterns and development practices. In this talk, we’ll look at what serverless architectures are and how you should use them. We’ll dive deep into features you should look for in your architectural components and those you should avoid.

When Monitoring falls in love with Observability

Users have funny and unpredictable ways of using a product. That is a fact, not an assumption. Can we even think of all those wacky patterns upfront? Functional and performance tests are our way of trying to mitigate them, but are we aware of how our system behaves on production? What happens when the product we build goes finally “live”? Do we observe what is happening with it? Are we learning from our observations? 

I’ll share a story about how my daily job used to consist of monitoring our system in production and learning from it. Some of the lessons that we found along the way are: 
– oracles for our performance tests 
– learning about system behavior 
– observing (potential) errors in the systems 
– preventing bugs from getting to users before we fix them 
I’ll show you which tools we used and how we used them and what we could see by observing them all together, because one tool is never enough.

Applying GitOps To Everything

You are likely already using GitOps for your applications, but not for everything else. You are likely not using Argo CD, Flux, Rancher Fleet, or similar tools to manage the state of your infrastructure and services. Why is that? If GitOps is a great solution for apps, isn’t it safe to assume that it would be equally beneficial for anything else? What is missing?  

The problem is that most of the commonly used GitOps tools are managing Kubernetes resources which, traditionally, do not deal with infrastructure and Cloud services. That’s what we need to change. We need to expand Kubernetes with custom resources that can manage anything, no matter whether that’s AWS, Azure, Google Cloud, GitHub, Elastic, DataDog, or any other Cloud service. If we do that, we might convert Kubernetes API into a universal API. We might convert the Kubernetes control plane into a universal control plane. If we do that, we will get end-to-end GitOps through which everything is always in sync and where all we have to do is push changes to Git repositories.  

All we need to make that happen is Crossplane (an open-source project donated to CNCF), combined with Argo CD, Flux, or Rancher Fleet. Let’s see it in action.

Tangible Software Quality – KEYNOTE SPEECH

What quality aspects can even be captured by testing, and what types of quality activities need to happen in development, or after deployment? Does a bug count really show quality? How much manual testing do we need to do, and what should we automate? How to make sure that all the key business values are properly represented and evaluated during delivery?   

These are fundamental questions that any software team needs to answer, but it’s very difficult to find a good strategy for all this complexity. Sigurdur and Gojko will present a model for making software quality tangible to all the stakeholders, with an example from the IKEA Planning Experiences team.  

You will learn how to facilitate a conversation about what high quality delivery means for your organization, and how to create your own tangible software quality model that will capture all the important business and technical metrics and risks.
