I need you to create a database server for me

I am looking for a database engineer / Web developer / Backend / Fullstack developer who can setup a database server for me. All the data is already present. You simply have to bring it together on a single database server. This is a one time project but could result in a beneficial consultant-like offer which could be very lucrative for you. It could be hosted on AWS/ Locally or anything else Currently, I have two vendors. Who's apps we use. One vendor uses Azure MS SQL, the other vendor uses MongoDB. The goal is to get the data from the database of both these apps and to store it my own database. Just bear in mind that whatever solution you propose, you must know how to implement it end to end and that it should be able to take the load 50 users interacting with the database on a daily basis. Later on, we would also like to add an analytics dashboard on top of this database so it is necessary that to have this is mind while implementing your solution. The only preference is that the tooling and resources used have to be open source. Rest assured, You will get full support from the vendors and autonomy to implement whatever solution you prefer. As you may see, we are totally open to your suggestions in case you think something else is better than AWS/ Local hosting. Feel free to message me here if you have any questions. As a starter, you can begin my sending me a message on what solution you would implement and how would you go about it. Looking forward to your quick response Cheers!
