Wordpress is system with a rich ecosystem of plugins. There is a plugin for anything you can imagine, some of them have a cost but most of them are free. Here is my personal list of plugins I used in the last blogs I've built with Wordpress. All of them are FREE and some of theme have a paid version but are fully functional in the free version.
The past week I backed for two projects. Every time I was minimally interested in a crowdfunding project where about physically products that need the fundings to make the production so I never decided and finally never backed. But this time I found two projects that really interested me and I think that they can help me in my work and development career.
