I am from India but recently moved to Berlin, Germany. I want to be flexible with my location as I want to travel in the future and work from anywhere. I should not be required to travel to the country of incorporation for legal purposes etc. 

I am working on a project where I have partners who provide services and customers who use those services by paying some amount. I am using Stripe for processing payments. What are some common mistakes that people do while implementing this?

I want to have a website where I do small fun and creative tasks. As a part of that, I created my first project which is getting top 100 referenced books on fs.blog. You can see those here. https://brahma.fun/top-100-fs-books

I am using node, express, and apollo graphql on backend. Sending beautiful emails is one of the core features of the project. Any recommendations on good node styling libraries would be really helpful.

I am using Heroku to deploy my project and mlab for mongodb database. Now I want to store the profile pictures somewhere. Storing them in mlab is not a good option. The only option I can think of now is using a CDN? How are you storing images?
