Upwork Freelancer 012d3e16 — Web Scraping & Data Extraction freelancer in Gujranwala

Your backend is leaking revenue. Slow queries, blocked scrapers, and manual workflows are costing you 40+ hours a week and you already know it. I am a Full-Stack Engineer who builds the complete automation engine: from Python scraping pipelines that treat Cloudflare and Akamai like they aren't even there, to high-performance FastAPI backends and production Next.js SaaS platforms. As a Top Rated expert with a 100% Job Success Score, I deliver production-ready systems not MVPs that require rewrites in 6 months. Most engineers own one layer. I own all of them which means your project ships faster, costs less, and has zero integration failures between frontend and backend. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🚀 HIGH-VALUE SOLUTIONS I PROVIDE 🛡️ Advanced Anti-Bot Bypass Specialized in defeating Cloudflare Turnstile, Akamai Bot Manager, and PerimeterX using stealth Playwright configurations and residential proxy rotation. I have architected systems processing 1M+ requests daily without bans solving the blocks that stop other developers permanently. ⚡ Scalable FastAPI Backends Architecting asynchronous REST APIs with PostgreSQL (JSONB architecture) and SQLAlchemy, featuring automated Swagger documentation, Alembic migrations, and Celery + Redis task queues. Built for 99.9% uptime and query-tuned to significantly reduce your server costs. 🌐 Full Stack SaaS Platforms Building production Next.js 14 (App Router) platforms with TypeScript and React Query multi-tab workflows, real-time data views, and a clean 5-layer architecture that remains maintainable as you scale to thousands of users. 🤖 AI-Powered Data Pipelines Integrating OpenAI API, Gemini, and LangChain to clean, classify, and structure raw extracted data with 99.9%+ accuracy. The result is decision-ready data not a spreadsheet you still have to clean manually. ⚙️ Async Workflow Architecture Implementing Celery and Redis for heavy workloads real-time data processing, automated lead generation, and scheduled jobs without blocking your main API thread. ☁️ Cloud-Ready Infrastructure Secure, containerized deployments using Docker and AWS (EC2 \u002F S3 \u002F Lambda) with full CI\u002FCD pipelines.
