visual studio database connection change oracle to postgres

I am looking for someone to help me make a change in our database connection from Oracle to Postgres. Our environment is a remote server and we do have an existing Oracle database that we need to use to retrieve data. This project will require the expert understanding of database fundamentals in both Oracle and Postgres and the ability to troubleshoot any issues that may arise. To complete the project, we require an experienced database specialist who is familiar with and comfortable working with the necessary tools to make the change from Oracle to Postgres in our remote environment. The successful completion of this project will result in the necessary database connection change for our organization and a reliable database connection with Postgres.
