Hello,
As an experienced senior web and mobile developer, I believe I have the skills and knowledge necessary to integrate UnionPay as a payment method into your WooCommerce platform. My proficiency in PHP, including in-depth familiarity with its application in Yii2, Laravel, and NoSQL like MongoDB, coupled with my extensive experience with payment integrations, particularly in eCommerce platforms such as WooCommerce, give me the edge required for this task.
I also possess a Tech Savvy mindset with working experiences ranging from Back-end Development (complete with testing using PHPUnit) to Front-end Development in JavaScript libraries such as Vue.js, jQuery, and some AngularJS. My sound understanding of HTML5, CSS3 (LESS, SASS), alongside my expertise with databases like MySQL, PostgreSQL, and Redis enable me to build complex queries for the fastest search/filter responses which is a key attribute needed for efficient payment integration.
Thanks
