Project Refactoring (Rename) And Testing

We have several apps that need to have some refactor by renaming variable names, package names, etc. We also need to ensure all the apps in the repo are working properly. So you need to run and test the app as well. Our apps are written in various programming languages. Followings are the role and the technical skills required in order to work on this project:

Fullstack Developer (3 yrs + exp preferably).
- PHP
- Python
- C ++
- Jenkins
- Kubernetes
- Java

We have 26 projects to work on this in total. More specifically, we have 16 apps that needed to be run and tested to see working or not for major functionalities and the other 10 apps to be refactored to rename and tested as well.
Let us know if you're interested in this.

Looking forward to seeing your application. Thanks!
