Hi there,
I am a cloud engineer I will host your node.js application in any cloud platform.
I will also connect your application to mongodb. I will complete your work in 2 hours. I will connect your application with website too.
Contact me for more details.
It's great to know your selection as per application built platform.
I can build Node.js webservices with MongoDb as database linked to them.
I can deploy it on AWS Console Instances or we can go for serverless architecture, whichever suits you.
Consider this win-win for both of us.
hope to see our connect soon.
