  • Leading Healthcare Provider | Oracle Webcenter Architect (Development)

    Oracle WebCenter Architect is a Java-based web content management system running on AWS infrastructure to power 30+ websites for a major healthcare provider.
    I worked on the application team that managed the infrastructure and took the lead development and architecture roles for the large extended development teams (eight teams in total). I created an innovative static publishing and caching system that used Python to extract HTML data from the Oracle system to speed performance from 2-3 second load times to 300 milliseconds. I also managed automation for patching and upgrades across 100+ AWS servers.

  • US Cellular (Development)

    US Cellular needed to replace the dated Documentum-based content management system that powered their intranet and extranet-based agent knowledge portals. Xumulus partnered with the internal IS teams to deliver an innovative solution that leverages Oracle WebCenter sites (OWCS), Oracle WebCenter content (OWCC), and third-party security solutions using both Apache mod_mellon for SAM and Apache mod_auth_kerberos fully integrated to their IAM back end. This allowed external and internal teams to authenticate seamlessly to the new portals. We implemented the Oracle WebCenter sites' 12c platform. The front-end solution was designed to be served off a single OWCS site but used the sites' security context to personalize the site content. Thus, management overhead in creating and managing content across two sites was reduced. Additionally, this allowed for a personalized user experience based on rolls with the organization.

  • Constellation Brands (Development)

    Oracle digital asset management system with various modifications. The system was built with Oracle WebCenter content and had several java-based modifications as well as building custom web-based UIs using REST services and jQuery.

  • Jackson Family Wines (Development)

    As one of the premier wine families with over 60 brands under its umbrella, Jackson Family Wines needed a solution to allow its channel partners to quickly navigate and find all brand assets housed in its Oracle digital asset management system. They needed a solution that would be easy to implement and to leverage the tens of thousands of assets already in its digital asset management system. By using this system API and by implementing special indexing techniques we were able to create a website that allowed users to find assets using faceted search. Allowing users to quickly hone in on the assets that they were looking for, download them and repurpose them in their marketing and customer-focused activities. TheKey is a huge part of bringing their many brands to market.

  • NTWOnline.com Magento to BigCommerce Migration (Development)

    I migrated a website from Magento 2 and fully integrated it with Mail Order Manager (MOM) to Big Commerce. Also, I used Hawksearch to enable search and search filtering. This increased conversion rates post-launch by 90% and page load time by 40%.

  • Major Audiophile Website Magento 2 to BigCommerce Migration (Development)

    I migrated the website from Magento 2 to Bigcommerce while maintaining many custom features from Magento, product attachments, product customizers, and CMS Page customized menus. I also created a new Cornerstone Stencil theme to support the same front end as the Magento store had. Finally, I migrated all products, and page and blog data.
