Our CodeIgniter-based platform is live but a handful of issues are blocking final rollout and I need them resolved right away. What needs attention • Bugs in core flows: login & registration, payment processing, plus several data-display / retrieval screens are throwing intermittent errors. • Performance clean-up: tighten up slow database queries, streamline controller / model code for better efficiency, and shave seconds off overall server response time. • UI polish: a few front-end inconsistencies remain after recent updates and must be brought in line with the existing Bootstrap layout. You’ll be working directly in the existing MVC codebase (PHP, CodeIgniter, MySQL, jQuery). SSH and Git access are ready; as soon as you confirm you can start, I’ll grant credentials and point you to the specific routes, queries, and views that are misbehaving. Deliverables 1. Stable, error-free login, registration, payment, and data views. 2. Optimised queries and refactored code sections documented with brief inline comments. 3. Noticeable reduction in page load / API response times, validated on my staging server. 4. Clean user interface on all affected pages with no broken elements across desktop and mobile. Please respond only if you can dive in immediately and push fixes today; time is critical.
