My business site is already live on a lesser-known CMS, but it still needs a solid full-stack pass: squash the remaining bugs, fine-tune performance, and then deploy cleanly to production. The current codebase mixes PHP and vanilla JavaScript; server access (SSH and cPanel) is ready, and DNS can be pointed as soon as everything is stable. Here is what I need from you: • Review the existing code and database, identify breaking issues, and fix them without touching core CMS files unless absolutely necessary. • Optimise load times and remove any console errors so the site scores well on Lighthouse. • Configure staging → production workflow; I’m happy with Git-based or any simple CI solution you prefer. • Final deployment to my VPS, followed by a quick smoke test to confirm all pages, forms, and payment gateway are functioning. • A short hand-off note covering what was changed and how to roll back if ever required. The project centres on a WEBSITE, built on an OTHER CMS rather than WordPress or a traditional custom stack, so your adaptability matters more than the exact framework you favour. If you’re comfortable diving into someone else’s code, cleaning it up, and shipping it confidently, I’d love to get started.
