Data analysts have to check the work of web crawlers by verifying number of ads and their content. In autobiz SA, we have a huge number of websites to crawl. Suppose that all the data analyst work in this step is manually then it will be surely a large loss of time. This is why, we worked in the company on a tool that automate the part of counting ads with notification by mails to the analysts.

Crawling currency from about 18 sources in an OOP selenium project.
The currency banking pages have some similarities and the great number of sources was a real challenge. To facilitate updates and readability, I used the OOP concept to deal with the webdriver as an instance. Also, I used many python tricks to avoid redundancy and optimize code.
The output was a pretty flask API.
Technologies: python, selenium, flask
