“I attended the event in Madrid at Playtomic's offices: the atmosphere was fantastic, surrounded by top company leaders. I remember debating a particular architecture and sketching ideas on the whiteboard. Afterwards, we went out for beers. There are very few events like this.”
Carlos Karus
CTO at AWS EMEA
“I joined the first event in Barcelona and gave a short talk about what it means to be a great engineer in the age of AI. I met amazing people and we went out for dinner together afterwards. I'll definitely be back for the next one.”
