Project to create a social network

I need a creative and discreet developer capable of developing a tailor-made social network with unique and currently non-existent functionalities. The project is 100% confidential and the developer will have to sign a confidentiality agreement before having the details of the project. I would like the social network to be accessible on a mobile application (compatible for all phones) and also usable from the website exactly like Facebook and Tiktok. To better guide you, note that the social network must have all the features of Facebook and more, with the possibility of adding scalable features over time. So you will have to choose a programming language that could allow this and be flexible. The user must be able to choose their languages ​​(preferably all languages ​​available on Facebook). I would like a proposal that covers everything: the total cost of the application, the site, availability in all languages, the confidential nature of the project. NB: I favor developers who have all of the following • No beginners • Be able to communicate with me in French • Agree to keep the project confidential under penalty of legal proceedings I will appreciate if you have knowledge of international jurisdiction for the launch of social networks, or if you work with lawyers who can help bring the application into legal and international standards.
