Visual Basic Program Upgrade Testing

We need a freelancer with 5 / 10 years experience to test an upgrade for a Visual Basic program that is more than 20 years old. The work involves reviewing the updated application, identifying issues, and ensuring the upgrade functions correctly across key workflows. You should be comfortable working with legacy systems and providing clear feedback on bugs, performance, and usability. This is a short-term project for someone who can test thoroughly and communicate findings effectively. (Must provide at least 3 examples of having done a similar job before).
