Find deals before they appear on the eBay website/app, game, system and accessory collection tool, custom blog and much more.
Technologies: Laravel 5, AngularJS, Pusher, Bootstrap, SASS, MySQL, eBay API
No longer maintained but worthy of a mention. At it's peak it got thousands of visitors each week, the app still gets a fair amount of use.
Technologies: CodeIgniter, jQuery, MySQL
