Thanks for reading my article and also reaching out to me.

The best method of showcasing your interest in Machine learning to potential future employers or anyone is to have any project that you've worked on accessible online. You can either have a dedicated weblink for projects or a GitHub link for code repos of the projects you have created.

Also, it's very important that your project showcases the extent of your abilities. A more simple direction would be to pick a common problem that you have observed and see how machine learning can solve that problem. Your devised solution could then be made accessible for individuals to assess and use.

What worked best for me in terms of showcasing my ML skills is writing Medium articles. I would advice that you write Medium articles on ML concepts and techniques you have learnt.
