  • Ensure reliable extraction from dynamic and interactive websites, including JavaScript-rendered content and changing site behavior.
  • Enforce data quality standards through validation checks, cross-source consistency controls, formatting compliance, and systematic verification before delivery.
  • Scale scraping operations for large datasets using batching or parallelization, while monitoring failures and maintaining stability as sites change.

  • Solid background in data cleaning, normalization, and validation, with delivery of structured datasets in CSV, JSON, or Google Sheets.
  • Demonstrated experience handling anti-bot mechanisms and dynamic site structures at scale.
  • Experience with cloud infrastructure such as AWS and containerization with Docker in real workflows.
  • Hands-on experience with LLM frameworks such as LangChain, OpenRouter, or similar automation tools.
  • Upper-intermediate English proficiency (B2) or above.
  • A GitHub link is a plus.

Benefits

  • Estimated workload of around 10–20 hours per week during active project phases.
