    I am webscraping and data extraction expert. In more than 7 years working in this field, I have scraped more than 1500 different kind of websites (simple html, with javascript, with protection - limited number of requests, with login...) and save data in different formats or databases (.csv, .xls, .json, MySql, MongoDb, AWS DynamoDB, AWS RDS, AWS S3...). One website had ~130 millions of records (simple html and it was done for ~10 days). I am using proxies for rotating IPs so on every request I have different IP address. Also have big experience in scraping e-commerce websites like magento1, magento2, shopify, opencart, bigcommerce, woocommerce.... The tool I am using is my own code written in python, but I can use scrapy too. I am fast, efficient and responsible and I can find solution for most of problems online. So learning new things is not problem for me. If you are interested in collaboration - contact me anytime so we can make a deal. I am in Serbia, Europe, CEST time zone.

    Sergei here. I am not the most talkative guy and prefer my work to do the talk. You can check my portfolio here github.com/javaPepper. As you can see, I custom-coded various websites, ranging from simple SPA to complex platforms. Apart from my work, which is my greatest passion, I enjoy running and cycling. Honestly, it is important to balance the long hours we spend in front of a computer screen with some physical activity, and that’s exactly what I do in my leisure time.
