How many Projects should you add to a Portfolio?

Given that you're not starting from scratch, asking about the quantity of projects you showcase in your portfolio isn't the right question. What you should be focusing on is the type of projects you're showcasing and the quality of those projects and the portfolio as a whole .

• I would ditch the JavaScript blog in the showcase, put it somewhere else in your site like the Nav. You have enough other projects that you don't need it.
• You're wasting an incredible amount of space in your showcase, and if I was the hiring manager reviewing your candidacy - I'm unlikely to read all the way to the bottom because of it. If you're going to use a two-column layout for your showcase, then each column in a row should have a project.
• You have some amazing content in your showcase (UX study) but I also see some content that is not worth my time reading. This showcase for example should be reworked to flush out the content sections further or eliminating several of them.
• I get 404s if I click code links for several of your projects, either fix the link or don't promote that i can see the code behind the project
• JSON is not a skill.
• Several of your layout or content choices baffle me. Why is there a row of icons with no context? I see what looks like a trello board and slack icon, are you telling me that you've done work for those companies or that you use those tools? If you're telling me you use slack, it's like telling me you're familiar with Microsoft Word - it's not worth highlighting.
