Expected duration: 1 - 6 months Advanced Web Scraping Specialist for Amazon Price Monitoring and Notification System Duration: 3 - 6 Months (Possibly Longer) Start Date: ASAP
Overview: We are seeking an experienced and highly skilled freelancer to create a complex web scraping system that will monitor product prices on Amazon in real-time. This system must be able to efficiently scrape Amazon's product listings, detect price changes, and notify users of these changes with high accuracy and speed.
This project requires a strong understanding of web scraping, API integration, and advanced data handling techniques. You should be comfortable with large-scale data extraction, working with multiple product categories, and managing frequent updates.
Key Responsibilities: Web Scraping: Build a scalable web scraper to extract product data (price, title, product description, reviews, etc.) from multiple Amazon product pages. This includes handling pages with dynamic content and CAPTCHAs.
- Price Change Detection: Implement a robust system to track price changes for thousands of products on Amazon in real-time. Ensure that the system can identify price fluctuations, including minor adjustments. Notification System: Develop a user-friendly notification system that alerts users when a product price changes. Notifications should be sent via email or push notifications (based on user preference). - Data Storage: Build an efficient data storage solution for the scraped data, ensuring historical price tracking is available. You must optimize storage and retrieval of large volumes of data. Scaling: Ensure that the scraper can scale effectively, with the ability to handle high volumes of products and frequent price updates. - Accuracy & Reliability: The scraper should minimize errors (false positives/negatives) in price change detection and be able to handle rate-limiting and anti-scraping mechanisms implemented by Amazon. - User Interface (Optional): If feasible, create a simple front-end interface where users can track their selected products, receive notifications, and customize their preferences.
Follow best practices to avoid being blocked or banned by Amazon.
- Required Skills & Experience: Advanced Web Scraping: Proven experience with advanced scraping techniques using tools like BeautifulSoup, Scrapy, Selenium, or Puppeteer. - API Integration: Strong experience with integrating third-party APIs, especially for notification systems (e.g., SendGrid, Twilio). - Real-Time Data Processing: Expertise in setting up real-time data pipelines and event-driven architectures. - Cloud Infrastructure: Knowledge of cloud platforms (AWS, GCP, Azure) to deploy the system and manage resources efficiently. - Data Storage & Databases: Proficient in designing and maintaining databases, with experience in relational and NoSQL databases (PostgreSQL, MongoDB, etc.). - Programming: Strong knowledge of Python, JavaScript, or other relevant languages. Experience with multithreading, async programming, and handling large-scale data. - Anti-Scraping Measures: Deep understanding of IP rotation, proxy servers, CAPTCHAs, and other countermeasures to avoid being blocked by Amazon’s anti-scraping mechanisms. - Attention to Detail: Ability to deliver accurate and well-tested solutions with minimal oversight.
Nice-to-Haves: - Experience with Headless Browsers: Familiarity with using headless browsers (e.g., Puppeteer, Playwright) to interact with dynamic Amazon pages. - Machine Learning: Experience with machine learning for detecting patterns in price changes or predicting future price trends (optional but a plus). - Prior Amazon Scraping Projects: Any prior experience scraping Amazon and handling its anti-scraping protocols will be an advantage.
