Last week, NN Group officially launched the NN Digital Hub in Spain. As a key technological driver within NN, the Hub represents our commitment to innovation and technology. The launch coincided with the leading tech conference Codemotion Madrid 2025, providing an ideal opportunity to introduce the Hub and connect with the Spanish tech community.
At Codemotion, NN showcased how we are not just keeping up with tech innovation, but actively shaping it. Over two days, our team immersed themselves in one of Spain’s top tech conferences, connecting with over 2,000 developers. More than 40 colleagues attended, and developers from the Hub delivered their first-ever tech talk on stage. Our presence at the conference highlighted our role in driving forward-thinking solutions across the organisation.
Tech talk - The fundamentals of frontend development
During the tech talk on Wednesday, colleagues Miguel Martín López, DevOps Application Engineer, and Roger Sanz Cortés, Frontend Engineer, spoke about how developers can build faster, more efficient web applications using modern React techniques. The goal of the talk was to show some commonly unknown facts about React and also to inspire attendees to dig into technologies and learn how they work internally. So that in the end, they can create better and solid solutions.
The talk explored some of the deepest concepts of React. It started with an easy introduction to the technology for beginners and then explored rendering concepts and phases. It covered hooks, components, higher-order components, and how they all work in the reconciliation algorithm. Miguel, one of the speakers and DevOps Application Engineer at NN Digital Hub, gave his thoughts on visiting Codemotion and their tech talk:
‘During the event, we had a lot of fun with colleagues and attended many interesting tech talks. When it was our turn, we tried to inspire and give ideas and examples to the attendees, emphasising that there is no magic in the technologies we use, just code written by expert developers that can offer rich knowledge to those who explore it. We are very happy with the positive feedback!’
The NN Wordle game made a comeback
The energy at the NN booth was contagious. A diverse group of colleagues from across NN (Czechia, Slovakia, Spain, the Netherlands) came together to represent the NN Digital Hub, share their expertise, and connect with fellow tech professionals. One of the highlights was the return of the NN Wordle game, custom-built by our developers, which once again proved to be a fun and effective way to spark conversations. The game drew a steady crowd and gave our team a chance to talk tech in a relaxed, engaging way.
Our booth stood out not just for its interactive elements, but for the genuine enthusiasm of our team. We were proud to share what it’s like to work at NN and how we are building empowered, diverse teams that deliver socially responsible digital products.
Growing the global NN tech community
Beyond showcasing our tech, Codemotion Madrid 2025 was a powerful platform for attracting new talent. With meaningful conversations and a strong interest in our open roles, the event helped position the NN Digital Hub as an exciting place to work for tech professionals in Spain and beyond.
Codemotion Madrid 2025 was more than just a launchpad, it was a statement. The NN Digital Hub is here, and we are ready to collaborate, innovate, and grow with the tech community in Spain. We are excited about what’s ahead and look forward to continuing the conversation at future events.
