I built an online marketplace featuring tools, templates, and assets for creative professionals. Stand out features include a drag and drop product presentation builder, an advanced search system, and a unique revenue sharing system that I built from scratch.

I achieved the required functionality by integrating and heavily customizing a number of WordPress plugins, including EDD Frontend Submissions, SearchWP, FacetWP, myCRED, Elementor, and many more. I also developed a custom child theme for the site and integrated a number of third party services including Tipalti (mass payments), TaxCloud (sales tax compliance), and Dropbox.

Technologies: PHP, HTML, CSS, JavaScript

Simple Sales Tax Plugin

Simple Sales Tax integrates TaxCloud with WooCommerce to make it easier for merchants to comply with US sales tax laws. I developed Simple Sales Tax in January 2014 and served as the sole developer and support agent from then until FedTax acquired it in February 2017. Though I have since retired from customer support, I still maintain the plugin in my role as a FedTax contractor.

Technologies: PHP, JavaScript, HTML, CSS

Payouts Integration for WC Vendors
I developed a WordPress plugin to enable WC Vendors Marketplace users to quickly, easily, and securely pay their vendors using the PayPal Payouts API. I handled all aspects of the development process, including UI design, front-end development, back-end development, and testing.

Technologies: PHP, HTML, CSS, JavaScript

Matcha Source Website
I built a beautiful, responsive WooCommerce storefront for Matcha Source, a retailer of matcha tea and accessories. Along with implementing the theme from scratch using provided PSD designs, I successfully migrated thousands of customer records, orders, and active subscriptions from the existing Volusion store using the Volusion API. The site still serves tens of thousands of visitors every month.

Technologies: PHP, JavaScript, HTML, CSS

Marketplace Taxes Plugin
I developed a WordPress plugin to enable Dokan and WC Vendors marketplaces to use TaxJar's SmartCalcs API to automate sales tax calculation, reporting, and filing. The plugin was built with the specific sales tax needs of online marketplaces in mind and included an option for marketplaces to collect and remit tax on behalf of their vendors.
