Please review my backend projects

Just finished two backend projects.

Here is the github project.

Any comment/criticism/feedback is welcome.

Hi, good job! They both work as expected. The only thing I noticed: the timestamp microservice returns: {"unix":1450137600000,"natural":"December 15, 2015"} on this url:,%202015, but on the landing page it says that it should return: { "unix": 1450137600, "natural": "December 15, 2015" }.

Both are correct, but it seems like you accept a Unix timestamp with seconds, but return one with milliseconds.

okay will change that.
