Node.js Backend Migration to Hostinger VPS

I'm looking for a developer to help me move the Node.js backend from localhost on a personal device to a VPS hosted on Hostinger.
VPS is already running with the frontend setup on apache2 and working; 82.112.227.196 or system.beyond-behavior.net
Need to move the backend written in node.js and teach me how to do that next time.
The system status is as follows:
root@rqb:/home/rqb# node -v
v20.16.0
root@rqb:/home/rqb# npm -v
10.8.1

root@rqb:/home/rqb# sudo systemctl status apache2
