Dear Hotel Developer,
I have 4+ years of experience as a python developer. My projects have been into versatile domians like scrapping, cross platform application development, web app development (Django), database handling, networking, AWS, Google App engine and so on. I recently completed a quite similar project it was based on implementing Google places API (https://www.freelancer.com/projects/python/upgrade-google-places-api-script/). I checked the populartimes repository, seems simple to implement also the documentation seems to be good. The conversion of JSON to MongoDB can be achieved by creating a pyobject of json and converting the pyobject to mongoDB or if you want the json data can be directly updated to MongoDB using pymongo. Please feel free to discuss.
Thanks..!!
