Hello Andrey,

I can not proceed with this budget. This is not a task where automation can be used to simply upgrade the packages. Even if I attempt to use automation tools to complete the work within 35–40 hours, it is not realistically possible.

Moreover, even if such tools are used just to upgrade Laravel, I cannot assure that the application will run smoothly and without performance issues.

As per my approach, the work is not limited to just upgrading Laravel. It also involves restructuring the API integration flow and optimizing the code for better performance and stability. This is why the timeline I mentioned (35–40 days) is necessary to complete the task properly.
