I worked as a Python Developer specializing in web scraping, product data extraction, automation, and backend development. My role focused on building reliable, scalable scraping solutions capable of extracting structured data from eCommerce websites, marketplaces, business directories, and dynamic web applications. I developed web scrapers using Python, Scrapy, Playwright, Selenium, BeautifulSoup, and Requests to collect large volumes of data while handling JavaScript-rendered pages, pagination, infinite scrolling, AJAX requests, login authentication, cookies, proxies, rate limiting, and anti-bot mechanisms. My primary expertise was product scraping, extracting detailed product information such as titles, descriptions, prices, discounts, SKUs, categories, specifications, images, ratings, reviews, stock availability, seller information, product variants, and metadata. I ensured high-quality datasets through data validation, cleaning, normalization, deduplication, and transformation before exporting them to JSON, CSV, Excel, SQL databases, or REST APIs. I also built backend services using Django, Django REST Framework, and FastAPI to manage scraped data, automate scraping workflows, schedule crawler jobs, process collected data, and expose APIs for seamless integration with client applications. My achievements include developing reusable scraping frameworks, improving extraction speed through asynchronous processing, automating large-scale data collection, reducing manual effort, and creating production-ready systems with proxy rotation, browser automation, retry mechanisms, logging, monitoring, and error handling. I delivered efficient data solutions for competitor analysis, price monitoring, lead generation, inventory tracking, market research, and business intelligence, helping clients transform raw web data into accurate, actionable insights.
