My Laravel-based platform relies on a sizeable MySQL database. Whenever a user tries to export or download a large data set the transfer stops midway, leaving them with an incomplete file. I need this resolved immediately. The job involves pinpointing why the current export logic fails, then rewriting or optimising it so that files of any size download fully—no timeouts, no partial data. You may want to introduce streaming responses, chunked queries, queues, or other best-practice techniques native to Laravel and PHP to keep memory usage low and the connection alive. I will give you access to a staging branch and a sample dump large enough to reproduce the problem. Your deliverable is a clean pull request with well-commented code, any new config settings, and a short markdown note on how to test the fix. I will consider the task complete once I can repeatedly download the full export without corruption or early cut-off. Time frame: ASAP—please indicate how quickly you can turn this around once you have the repo.
