We took over the management of Moon audio and helped solve several issues they were having with their Magento Commerce Build. There were many performance issues caused by their extensions and themes. Though they were not high on the customization scale they had enough wrong that it was wreaking havoc on the cache. After our fixes, page loads went from 4-5 seconds down to less than 400ms. Additionally, we helped stabilize their entire system and resulting in a record month of sales this last May. We also helped them with their Magento Commerce cloud setup greatly improving the deployment process. Oh, and we killed their slow Magento 2  product page image loader!
