I've been working on a hobby project after work and I've been learning a lot of new skills from it. But the "likes" text field has run out of space and this project is (temporarily?) closed source so I can't add these skills as a github repo. Where should I put these new skills? I'd like employers to know I can use these technologies even though I've never been paid to use them.
Here's an idea: I could add this as experience that overlaps the time span of my current job. But I'm not sure if this is the type of thing I'm supposed to add to that "Experience" section.
