Social Warfare is a very popular WordPress plugin which provides a set of social share buttons for your website. The core product has limited options, while the paid upgrade Social Warfare Pro expands the network choices and provides many more display, connection, and engagement options.
For 15 months I worked as Product Development Specialist for Warfare Plugins. The core product is active on 60,000 sites across the globe. The premium upgrade Social Warfare Pro enhances the core product by hooking into the core functions as well as passing through data filters.
Every month I pushed SVN updates to provide new features for plugin, keep it scalable across an arbitrary installation environment, and maintain the security and integrity of the software.
