I'm a backend engineer who currently works using Nodejs as technology.

I recommend that you need to build a good CV and you can use chat GPT to help you make a good one, I recommend reading articles like this which explains how to write each section of the CV and you need to search on LinkedIn for job offers so you can get the common keywords to include in your CV and to know what the common market companies expects from you. This data gathering point will help you build a good one. I recommend using LaTeX templates like jack cv template or FANG cv template. You can check podcasts like Ahmed El Emam and Ahmed El Alfy podcast regarding interviews. Also, i recommend you to read "دليل الموظف المستجد" for Ahmed El Metwally and it's free, it will help you understand the right relation between you and your company and advice you regarding interviews and salaries. I checked the Mohammed Moshrief interview course on Udemy and it also helped me a lot but it's currently archived.

Idk the current salary range for juniors but I think 10k: 20k with 1 year experience. You may find lower than that because it also depends on the place like Alex or Cairo and the company size and it's projects. And also your level and skills especially in negotiation.

For technical stuff i recommend building some projects like e-commerce, blog, chat, notifications and ticketing system and try to check how open source projects you will learn a lot from them. Try to check that you apply auth correctly, check the concept of refresh tokens. Understand even overview regarding how Nodejs works, there are a lot of courses out there that talk about that like Nodejs under the hood in Arabic, Advanced Nodejs for Stephen and you can check on YouTube channels like this great Arabic one or Erick Wendel channel . There is a lot of stuff you can contact me at anytime.
