For an existing application running in Express with mongo (not using mongoose) for the Backend and React JS on the Frontend, i am looking for a developer who knows best practices to accompany us for:
1. writing unit test with exhaustive test cases
2. refactorise the code base
3. improve existing code
4. add a few new features
The initial contract is for 1 month.
If successful collaboration, will extend to 3 months and it can be renewed for another 6 months.
An extensive knowledge of frameworks like Symfony or Spring MVC is highly appreciable.
