This gig combines backend automation with sophisticated data processing.
The Tech Stack:
- Extraction Engine: Python is the primary language, utilizing Selenium, Playwright, or Puppeteer for browser automation. These tools can render JavaScript, click buttons, and handle infinite scrollingtasks that BeautifulSoup cannot handle alone.
- Anti-Detection Layer: Integration of proxy rotation services (Bright Data, Smartproxy) and the use of undetected-chromedriver to bypass Cloudflare/Akamai WAFs (Web Application Firewalls).
- Data Processing: Once raw data is extracted, Pandas is used to clean itremoving duplicates, normalizing currency formats, filling missing values, and validating data types.
- Storage/Delivery: Data is delivered via CSV, JSON, or injected directly into the client's PostgreSQL or Firebase database.
