WordPress Backend Developer Needed

We need a developer to fix backend issues on an existing WordPress site. The work includes resolving PHP errors, improving database performance, and fixing product upload functionality so products can be added without issues. You should be able to diagnose problems, implement reliable fixes, and ensure the site runs smoothly after changes. Experience working on live WordPress environments and troubleshooting backend issues is important. This is a small, focused project for someone who can deliver clean, dependable results quickly.
