My web application needs a careful round of debugging and optimisation. The biggest headaches sit in the MySQL layer—query errors, slow statements, and the occasional data inconsistency that ripples through the site. Alongside that, a handful of logic errors and controller-level bugs in the Laravel backend have crept in. I’d like you to trace, fix, and test every issue so the whole system runs smoothly again. Here’s what the engagement looks like: • Database: profile queries, rewrite inefficient ones, resolve data mismatch issues, and verify indexes so response times drop. • Backend: clean up logic errors and controller bugs, then refactor where necessary to keep the codebase readable and performant. • Frontend: once the above are stable, confirm that Blade views display correctly and nothing new breaks. • Testing: regression tests (manual or automated) to prove each fix sticks. I value clear, regular updates and expect well-commented, optimised code committed to the existing repo. Do a solid job here and we’ll roll straight into ongoing maintenance and new feature work.
