This is more a process question that a technical one.

In what order do you develop a system with a front and backend ?

I'm trying to find out best practice, specifically for a travel search and book app, but i believe it generally applies to most systems.

I.e. Do you normally get the talents in, then UX and ui designs done, then code the frontend, then the backend, then integrate them?

That's my presumption but please let me know your experiences.

Thanks all.

I normally do :

Requirements
Design
Frontend
Backend
Integrate
Deploy
end to end test
General testing throughout.
