Many professional developers have also side projects!
Some have a commercial SaaS software, others an open source npm module ... others a blog!
There are also multiple reasons to have a side project: to update your resume, to make an extra income, to sharpen your coding skills or get new skills, etc.
Do you have a side project?
Talk about it! Tell us where we can find it, what makes it special, what technologies did you use, etc.
If you don't have one yet... would you like to build one?
