I have a lightweight Learning Management System that is live but struggling with two main pain-points: nagging functional bugs and noticeable performance slow-downs. The trouble shows up first in the login and registration flow—both admins and regular users hit intermittent errors that block sign-up or kick sessions out. On top of that, some pages lag badly whenever course data is fetched. I need a seasoned full-stack developer to dive into the codebase, trace the root causes, patch the bugs, and tune whatever is dragging response times. You’ll receive repository access plus a database snapshot so you can reproduce the issues locally, write clean fixes, and push tested commits back. Deliverables • Functional bugs resolved in the authentication and dashboard areas • Performance optimizations demonstrated by faster load times and lower server strain • A concise change log with setup notes so I can redeploy confidently Acceptance criteria: all admin and user sign-up / sign-in scenarios complete without errors, and average page response stays under 500 ms when simulated at 100 concurrent users. If you’ve squashed similar LMS problems before and are comfortable profiling both back-end and front-end code, let’s get this cleaned up quickly.
