Experience

  • Discover Healing
    https://discoverhealing.com/

    Discover Healing needed immediate and urgent performance optimisations to both the back-end and front-end of their WordPress installation.
    The back-end would regularly take over 60 seconds for pages to load, making admin a terrible chore. The front-end was averaging around 13 seconds for a pageload, despite caching. Previous developers had been unable to resolve the issues.
    ⇢ I was able to diagnose and fix hard-to-find issues with rogue plugins
    ⇢ I was able to improve the front-end load time by 60%, despite the requirement to stick with a heavy theme and third party tags
    ⇢ I wrote custom code to improve their user permissions
    ⇢ I wrote custom code to streamline the WooCommerce My Account system (including easy custom avatars)
