Question

Mobile development

I want to create an information portal about different services, tell me which services are better to use so that the web and mobile versions are synchronized.
Create a database engine on your own or use a CMS? what languages ​​do you recommend?
Thanks

Answer 1

What tools you know - use those.

Answer 2

Why own engine? CMS uses some kind of database - most likely MySQL. Accordingly, you need to write an API server that, upon request from a mobile application, will pull data from the database, format it somehow (JSON, ProtoBuf, etc.) and send it to the application. Accordingly, you don’t need to specifically synchronize anything, just resolve the interaction between the application and the site at the database level.
