How and where to find a teacher?

Question

Node.js

Hello.

I'm a layout designer. There are a lot of tasks at work related to the front, so there is not enough time for development or, for example, to take a project with a back-end at work and work on it, studying everything along the way + tired of freelancing in layout and front.

Maybe someone will tell you a contact or where to find someone who can give concentrated information and teach (for a fee), at the moment you need the following:

1. The optimal and fastest option for the browser to change content in blocks when you click on some buttons, it is desirable that the content in the code be written in a clear and neat form, ala json, since sometimes you have to make a static html site with 100500 identical blocks.
2. There are source files: index.html, main.css, main.js, всё залито на хостинг, также создана база данных.
Какие действия производит человек: в index есть input, вводим данные в него туда и нажимаем на кнопку.
Что нужно получить: нужна информация о том, какой самый быстрый и оптимальный способ отправки данных на сервер и записи в базу, а также как создать такой сервер и базу и мини API для приёма и записи данных.

Answer 1

1) codementor.io (choose tags there: the technologies you need and ru/rus/russian for example).
2) freelancing - create a task.
3) here on the toaster for users of interest to you (in the necessary tags again), see contacts - write in a personal.
4) ask some friends in IT companies to ask some of their friends to teach.
Your questions are:
1) javascript (obviously). You can write "content change" on buttons without using libraries, or with them.
2)
the question is too general. What's on the server? (probably MySQL database) What will you write the API on? etc.
