Write a Node.js and MongoDB application

PURPOSE:

Jacqueline Donald, hereinafter referred to as the client, is hereby requesting a proposal for the further development of a crawler/scraper page comparison tool/application that scrapes a popular consumer-to-consumer second-hand market for used iPhones in regular intervals and compares prices for iPhones per their model and storage capacity. The purpose of the application is to identify arbitrage opportunities, meaning ‘good deals’ on iPhones that can be bought and sold for a profit. The application, once identified such an opportunity, will notify the client by sending an e-mail to the clients Gmail account with the full details of the iPhone being advertised.

BACKGROUND:

The client has developed a fully functioning pilot application that runs on Node.js and uses an API from Apifier that fetches data on used/second-hand Apple iPhones. In its current state the application:

1. Fetches the data (i.e. information pertaining to iPhone advertisement) from the Apifier API on scheduled intervals.

2. Filters the data to include only Apple iPhones

3. Classifies the information per the model (e.g. iPhones 5s, iPhones 6 etc.) and memory capacity (16gb, 32gb etc.).

4. Inserts the data as documents into a MongoDB collection called ‘iphones’.

5. Analyzes all the records in that collection (the ‘iphones’ collection) to calculate the average price and saves the result into a MongoDB collection called ‘stats’.

6. Send an e-mails to the client’s Gmail-account with the details.

The client is requesting a freelancer or a team of freelancers to further develop the pilot application, meaning point 2 to 6 above, into a production ready application including more advanced data management in backend as well as improvements in the logic for filtering, classifying, transforming and analysing the data.
