Need a web scraping expert who can also build the backend around your data? I have 5 years of experience solving difficult extraction tasks, browser automation (Selenium, Playwright), session/cookies. I’ve built scrapers and data pipelines for different websites, where scraping is allowed. I always keep terms of service and do ethical scraping. I can deliver results in CSV, Excel, Google Sheets, send to your API, or ship the scraper itself. Just write me!
Recent projects:
• Scraped 200k car listings for an ML price prediction model using multiprocessing.
• Built a content-harvesting backend (pipelines + Google Drive/Sheets) used in production.
• Led a Django project that scrapes 100k+ content items (videos, articles, etc.) per week.
• Developed an internal Python library for PostgreSQL via asynchronous SQLAlchemy.
• Reviewed and fixed a client’s FastAPI project to improve reliability and speed.
• Built automation tools for various websites.
• Scraped transcripts for YouTube via an official YouTube API.
Tech stack:
• Python 3.12+, SQL; asyncio and multiprocessing for fast crawling
• Scraping: Beautiful Soup, Scrapy, aiohttp, requests; Selenium, Playwright; HTML, CSS, XPath, JSON,
• Backend: FastAPI, Django; JWT, OAuth2; PostgreSQL, SQLAlchemy (sync/async), SQLite, Alembic; Redis
• Data & automation: Pandas, NumPy; Google Sheets/Drive; Telegram API (Telethon, python-telegram-bot); OpenAI GPT API
• Dev & ops: Docker, CI/CD, GitLab, GitHub; pytest
If you need parsing, scraping, crawling, data extraction, data mining, or an automation script, just send 1-2 target URLs and a sample of the desired output columns. I’ll propose the best approach, the anti-bot plan, and a quick prototype. I always keep the terms of service.
I also handle data cleaning and enrichment with Pandas, plus ETL pipelines, so you get ready to use datasets. As a Python developer who cares about code quality, I write clean, readable code that follows PEP8 and OOP principles, and I cover key parts with tests for long-term stability.
Send me a brief description and technical requirements of your project, and I’ll solve your problem!
