Oleg Kolesnik

I am a Python developer with five years of hands-on experience in web scraping, ETL, and large-scale data processing, having built and optimized platforms that processed hundreds of millions of pages per month. I excel at designing robust scraping solutions using Scrapy, Selenium, BeautifulSoup and related tools, and I focus on data quality, validation, and performance optimization.

With background across gambling and other online/offline businesses, I bring over eight years working on online projects, strong QA sensibilities, and experience aligning engineering with business goals. I collaborate cross-functionally, document and train teams, and am ready to take on new challenges in project management, business development, or QA engineering roles.
