Utilize Serverless Architecture for Link Shortening service

Hello guy!
We just built as first ever fully serverless project this URL shortener - https://bx.vc
So far it works awesome and it’s huge win for architecture.

Would really appreciate if you can drop some feedback how it can be extended in useful features form native AWS services?

Like we going ot add Cognito to manage your links and so on.
Maybe there is some really elegant way to add Stats for links with existing services.
Looking into Lambda@Edge for geo customization as well

You may have something else to add and it would be really helpful.

Thank you very much!

btw, if there is any other place where serverless pals are handing out please invite me there. Would be happy to join community. Thank you very much!
