SQL and PostgreSQL
The Complete Developer's Guide

>Simplilearn << not this but yes about Linux Academy

Udemy Courses of Stephane Maarek - (
1. AWS Cloud Practitioner
2. AWS Solution Architect Associate
3. AWS Solution Architect Professional)
focus on getting a cert in AWS - like Solution Architect, so get his courses about that path. Once that nailed, you can move to AWS courses in Udacity, Cloud Developer and AWS Architect also in Packt u have lots of good books for AWS that are project related.

So in order to not bloat while learning, do one course at the time not parallels.

For PostgrSQL take this

How much do you know linux and docker?

Their "Foundations of EDB" postgres training seems to be truly free.

I can also recommend This for a quick intro to postgres SQL.

This is a more advanced course when compared to the first udemy course I linked to.

What's your goal: backend or ML?

In case of backend:

See - backend roadmap

You'll likely need to learn some framework (Django , Flask, etc..), SQL (#1 #2), Docker, Algorithms, be familiar with Linux systems, git, architect patterns (monolithic, microservices)

Here's a list of very good SQL courses for beginners:

3. https://www.udemy.com/course/sql-and-postgresql/

Learn Javascript. Its the most used language as its the language of the Web and Node is used extensively as a backend solution. Its package support is great. Its also, tbh, quite easy to learn relative to the other languages.

Start with Javascript - this is a good course.

Then you have the choice to either be a front end dev, ie websites, backend ie servers, or fullstack, both.

For front end, learn ReactJS. This course is decent.

For backend, learn NodeJS, a server framework like ExpressJS or Apollo Server, and a database solution ie MongoDB or Postgres (I would suggest Postgres - this is a good course). A decent course for Node could be this.

From there, I would recommend learning Typescript, and concepts such as Testing (particularly TDD) and CI/CD. This is a decent course for typescript.

Put yourself a portfolio together and start look at Junior Dev positions.

You can 100% turn your life around... I did. Hold down a part time job to keep some money coming in (or live off savings if you can), and just bang out these courses as though you were at school/college (ie 5-6 hours a day if you can manage). Once you've done say 3-6 months worth, you'll be able to get a first job. Once you get one (and you will, just keep trying, and if you need to, keep learning), you'll have your foot in the door and your life will change pretty quickly.

There are about about 300K Udemy courses on different topics. Of course, not all of them are good. But, from my experience, some courses are of very high quality.

Full stack web development. These courses are excellent for beginners in HTML, CSS, Flexbox, JavaScript, MongoDB, Node.js, etc.
