I and some friends created an application to a hackathon to truckers, the solution we created is called Sula and it's a social platform where truckers can ask for his rights and share experiences (we made this, because truckers have a lot of problems here). We have a lot of things to do to improve this app in this summer, and I will also translate it, so you guys can understand it 🙂
Backend with Node.js, TypeScript and GraphQL: github.com/sulatruck/backend
Frontend with React Native: github.com/sulatruck/frontend
Also, I think @Guilherme Farrel will publish the design of this app soon!
