Our company just started to contribute to WordPress by developing and distributing free plugins at the oficial WordPress plugin directory. We currently have three plugins, all of them related to WooCommerce, which can be seen at https://profiles.wordpress.org/hellodev#content-plugins.
Woo QR Code Generator – generates the QR code to WordPress users to integrate with WooCommerce API
Woo Calculate Total – automatically calculates the order’s total when saving a WooCommerce order
Woo Discount Admin Backoffice – allows administrators to apply discounts on orders from the administration panel.
Other plugins are being developed and will soon be released to all who want to try out their features.
We contribute to the WordPress community, your contribution could also make the difference.
