🚀 I built a Wolt-style food delivery app with React Native - from UI to maps to checkout flow.
This is one of my most complete apps yet - including a full Git Workflow 🔥
Built with @Expo.dev, @coderabbitai.bsky.social AI Reviews, Reanimated, @Sentry.io and more.

I think I'm finally taking on a new pet project and work on a mobile game.
I always wanted this.
It's financially probably a bad idea. Also time wise.
But since I was I child I wanted to be a game dev.
And maybe 2026 is the year it finally happens.

If you want to get away from Postman or Insomnia, check out Yaak for a great alternative 🔥

Expo Router has been such a game-changer for me.
It's still incredible to see how fast I can go from nothing to an app with nested drawer and tabs 😱
I don't think I can ever go back to a different way of routing...
If you are not using it - why? What's stopping you?
