Solving coding challenges on the LeetCode website is a great way to improve your developer skills. But an even better way to improve your skills is to develop your own LeetCode website.
We just published a course on the freeCodeCamp.org YouTube channel that will teach you how to build and deploy your own LeetCode clone.
The purpose of this course is to provide a hands-on approach to learning and implementing a bunch of popular web technologies. You'll come out of it with a fully functional coding problems platform, similar to LeetCode, which you can proudly add to your portfolio.
Burak Orkmez developed this course. He is a software developer and course creator.
