“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.”

“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.”
