Website Functionality Overhaul & Code Fixes

My website is already up and running, yet several functional gaps are holding it back. The immediate priority is cleaning up broken code that occasionally triggers errors, followed by a thorough optimisation pass so pages load snappily on both desktop and mobile.

A focal point is the user login system. I need it hardened for reliability and future-proofed for scalability—session handling, password reset flow, and any security loopholes must be addressed. Once it’s solid, I’d like the codebase documented well enough that adding extras such as social-media or single-sign-on hooks later won’t be a headache.

To keep us on the same page, here’s what I expect you to hand over:
• Debugged, fully working code pushed to my Git repository
• Refactored login module with clear comments and test coverage
• Performance improvements demonstrated by before-and-after metrics (load time, Core Web Vitals or equivalent)
• A short hand-off note summarising changes and future maintenance tips

Please bring strong PHP, MySQL, and front-end debugging skills to the table, along with a pragmatism that balances best practice with quick wins. Let’s get this site running smoothly and securely.
