Need a Node, Microservices, PSQL and GraphQL expert to help me via Team Viwer to solve a problem


Budget to discuss after a review of the code but I would prefer to not spend more than 100Euros if possible.

I have a problem to solve a scenario I encountered in my project and need support to solve it via Team Viewer.

The issue what I need to solve is related to the following scenario I have now:

I had to rename a column in a PSQL DB and I have to preserve backward compatibility with GrahQL within the system. The issue is that the column was named like contact and now I have contact_hours.

Due the system is based on many microservices the GraphQL should be able to resolve queries from old services not updated to the new field to get the data still.

So if a service requires contact should receive a result from contactHours and also some services send data in the same way so retro compatibility needs to be preserved.

I already started the changes but I got stuck with the retro compatibility itself and need an expert which can do this with me on TeamViewer as due to the complexity of the Docker microservices the setup require a week to be able to properly run everything on a new machine.

So please be able to help via a screen sharing solution where I will be guiding you around.

Thank you for the collaboration

I think you should handle this mapping in the code and not at the database level, because any change at the database level can cause issues at microservice level.
