Project History
Tooltip Glossary Plugin for WordPress
https://www.cminds.com/wordpress-plugins-library/tooltipglossary/Developed a very powerful WordPress plugin that includes a custom-designed and custom-coded parser using XPath and DOM manipulation library, allowing for automated and rapid building links to the internal glossary and glossary term pages. On top of that, the plugin allows displaying glossary definitions in tooltips and connects to multiple external APIs such as Wikipedia, Wiktionary, and Google Translate.
CM Micropayment Platform WordPress Plugin
https://www.cminds.com/wordpress-plugins-library/micropayments/A complete, complex solution for managing custom virtual currencies on one or multiple connected WordPress pages. I was behind the idea of this plugin and worked on the SQL database structure and PHP models required for it to work.
I also implemented the connection to the two major eCommerce plugins in the WordPress world: WooCommerce and Easy Digital downloads, which allow for the purchase of virtual points with real currencies, purchasing the products with virtual currency, or exchanging it for discounts.
