I run a data analytics consultancy in Sydney, Australia. I have a requirement to setup weekly scrapes of at least 5 large (50,000+ SKUs) online retail websites. The project will be split to scrape a single website to start with, extending to the others assuming satisfaction with the work completed.
- Scrapes must be written in Ruby using Mechanize/Nokogiri or Watir as appropriate
- Where possible, avoiding JS and scrape via direct HTTP requests using Mechanize - i.e requires strong skills in tracing/debugging HTTP requests/responses
- Alternatively, load page using Watir webdriver then pass off cookies to Mechanize
- Last resort would be brute force Watir webdriver approach (scroll, point, click, etc)
- Implement utilities for use of proxy / IP rotation where required (access to pool of anonymous IP addresses will be provided)
- Scheduling via cron job to run at least weekly
- Must use object oriented approach and design in a DRY manner so that code can be leveraged for future scrapes of additional sites and ensure future code manageability
- Must use Activerecord to persist records scraped
- Must implement logging (production logging to file + verbose debug option to STDOUT)
- Must be a great communicator both in terms of coding concepts and project management
- Good at clearly laying out the workplan, milestones and progress
- Must be available for 2x daily stand-up calls with Sydney AUS (timing TBC at mutually agreed time)
- Must be able to demonstrate prior experience with ruby web scrape projects similar to above
- Code must be well-structured and well-documented / commented
Opportunity for ongoing Ruby backend and RoR web app build if this project is a success.
