Magento 2.4.8 Upgrade

I need an experienced Magento developer to take my store from version 2.4.7 p9 to 2.4.8 p5. There are no in-house custom modules to worry about, but I do rely on several third-party extensions and want each of them updated to their latest compatible release during the upgrade.

The workflow I have in mind is straightforward: create a full backup, perform the upgrade in a staging environment, update and test every third-party extension, then push the changes to production once we’re both confident everything runs smoothly. Front-end styling, payment and shipping integrations, checkout flow, and admin functions should all work exactly as they do today—or better—after the move.

Deliverables
• Magento core upgraded to 2.4.8 p5
• All existing third-party extensions updated to their latest versions and verified compatible
• Post-upgrade testing (unit and functional) with documented results
• Rollback plan included in case of unforeseen issues
