Our tech moments

What we love about tech: sharing it! We meet and learn from each other through different tech rituals. Every Friday, everyone is welcome to the Tech Demo Presentation where we present new features and projects. On top of this we have weekly and monthly team meetings in our engineering teams to share progress on different topics.

We also organize coding nights to bring innovation, stimulate creativity and have a good time together!

"What I really enjoy is that it is a product that keeps improving. We are always launching new features, adding new travel modes"
