I built a centralised PHP-MySQL CMS from scratch and now need a skilled developer to take it to the next level. First, the page builder: it already lets me place predefined blocks, but I want to add a repeater-style system like user can be able to fredom add or remove list item. The end result should feel as smooth as Elementor or Gutenberg while staying lightweight and fully integrated with my current codebase and database schema. Second, the checkout form: everything processes fine up to payment, yet the final order-confirmation step intermittently fails to record the transaction and render the “thank-you” page. I need a thorough debug, clear error handling, and rock-solid confirmation logic that writes to the orders table every single time. Finally, I’m turning the whole platform into a multi-site system where any visitor can pick a theme from my repository, spin up a site instantly, and then customise it through the upgraded builder. That means creating the back-end routines to provision a new site, link it to the chosen theme, and expose only the right settings to the user while keeping everything secure and performant. Deliverables • repeater-style and template-customisation features added to the existing builder • Checkout order-confirmation bug fixed and tested end-to-end • Core multi-site/theme-selection workflow coded and working on my server I’ll grant access to the current repo, database schema, and a staging URL. Clean, well-commented code and brief implementation notes are all I ask in return.
