These plugins are built from scratch using PHP and jQuery (passes the WordPress Coding Standards), data are saved in the MySQL database, you can access its repository here to view the source code.
There are currently 2 plugins (both built for Trader Corporation's coding challenge), both need WordPress admin access to the admin side (to test this part, either install the plugin(s) on your own WordPress site or contact me to request login credentials to the demo.)
A plugin that allows the admin to add multiple authors (developers) to each post separately and display them to the front-end.
A meta box is added to every post-editor page to display all users whose roles are "author", the admin can then select which author(s)/developer(s) to be included for that specific post, the selection will be saved to the database when the post is saved.
(To access the admin side's demo, please kindly contact me to request the login credentials.)
A box will be displayed at the end of each post, it will display a list of users that were selected for that specific post, with their Gravatars as avatars, and clickable names that link to the webpages set in their profiles.
(You can find various posts on the website for demoing custom plugins to view some example boxes under each post)
A plugin that allows the admin to add, remove, reorder images to create a slideshow that can be added to any post/page.
A submenu page is available under Settings for the admin to either upload an image or select an existing image, alternatively online images can also be added by simply copying the URL into the field. Once the Add button is clicked, the image will be added to the slideshow list, then the admin can drag-and-drop each item to rearrange their orders of display in the slideshow. These settings will be saved to the database once the save button is clicked.

A simple slideshow will be added whenever the user adds the defined shortcode to any post/page, both the arrows on the sides and the dots in the center can be used to navigate the slideshow. You can find an example at this page.
