• Free fruits, candy and coffee, bla, bla, of course. But really:
• Ownership and autonomy above all, if this is your thing, own it!
• Open culture of discussion. There are no no-gos, if you have better arguments, we will change it.
• The freedom to own features, subsystems, topics. If you're good at it, you can be the guy for it.
• Any AI tool you want/need. We have access to all the latest AI tools and encourage their use. We don't vibe code but heavily use AI as a force multiplier.
• Whatever editor or setup floats your boat. You don't use vim!? That's weird, but ok.
