Having specialized in web scraping, data extraction (ETL), and data mining using Python, I am confident that I am the perfect fit for your project. Over the years, I've developed numerous custom scripts that scrape and extract data at a relatively fast rate from various sites including LinkedIn, Yelp, Zillow, Airbnb, Instagram, and YouTube just to name a few. Consequently, I have acquired deep skills in utilizing modern technologies like BeautifulSoup, Selenium, Scrapy to extract specific data without compromising on quality.
Furthermore, I have used different libraries such as Splash and Puppeteer for dynamic website scraping, ensuring no data is left unturned. This aligns perfectly with your project needs; to extract comments and submissions from a public Reddit dataset -a platform that is undoubtedly dynamic. Hence, my experience and skillset in utilizing these libraries will guarantee effective data extraction while also bypassing any security restrictions implemented.
On a personal level, I am committed to delivering quality work promptly. I understand the need for accurate data for research purposes and can assure you that I'll ensure all specified subreddits are included an organized CSV file; ready for analysis. Therefore, entrusting this project to me would assure you of high-quality deliverables within the stipulated timeframe.
