Online courses

Each Expert Coding course consists of several lessons. One lesson covers a subtopic of the course. You learn step by step and can set your own pace. We work on real tasks that you encounter in your daily work as a developer. The goal is not just to learn a topic; we are going to work a lot with Github to build a portfolio for you to prepare for job applications.

Learn JavaScript

To make the course more winning, I am not only follow the goal to successfully teach JavaScript.

The challenges in my JavaScript course encounter you in real life. So we will work on real web apps or small parts of a useful application that come together as the course is progressing.

Your work can be used to build a Github portfolio or to level up the Github portfolio.

To make it more realistic the challenges are different in some time in the course. To break down the complex, tasks are clear in the beginning, without any project reference. After some time a task is written as a user story in order to let you apply your previously obtained knowledge.
