Création d'un site web

We are looking for a web developer in order to create our website. The following is required:
1) Client-server communication
The most critical part of any web platforms is to establish a solid communication between clients and servers. You should be aware of the ways such a communication can be established, as well as all the design and performance issues related to it.
2) Client side rendering
When information is fetched from the server, you should be able to parse it and render it in a proper and efficient way whether you use pure HTML/JS, EJS, HBS etc…
3) Server side architecture
A server is the bulkiest part of a web platform, it should be properly setup and its architecture should be built in such a way that it is reliable, optimized and maintainable. We do not care whether you use Java, PHP, NodeJs etc…
4) Database Models
You should properly choose your models (Users/Journey/…) in order to perfectly integrate both the SNCF’s API and our server’s API responses into models that are readable and understandable.
