AVAILABLE 30+ HOURS WEEKLY | 4.5 Years AI and QA Engineering | 9 Years Professional Writing | Active Builder Most automation and scraping freelancers build things that work in demos. With 4.5 years as a QA Engineer, I build things that don't break in production. I know where systems fail because I've spent years finding those exact failure points—and now I apply that mindset to building AI, automation, and data extraction systems that businesses can actually rely on. 🔧 WHAT I BUILD ⚙️ Workflow Automation (n8n | Make | Zapier) End-to-end automations with built-in error handling, logging, and fallback logic. I don't just connect tools—I build systems designed to survive edge cases, unexpected inputs, and real-world chaos. 🕸️ Resilient Data Scraping & Extraction I build robust scrapers (Playwright, Selenium, Scrapy) designed to handle dynamic content, infinite scrolls, and complex site architectures. Because of my QA background, my scrapers include self-healing logic to alert you if a site layout changes, ensuring your data pipelines never go dark. 🤖 AI Agents & LLM-Powered Systems Custom AI agents using RAG, ReAct, and Chain-of-Thought workflows for lead qualification, document processing, and task automation. I specialize in taking raw scraped data and using LLMs to structure, clean, and categorize it into actionable business intelligence. 🔗 API & Backend Integrations REST APIs, webhooks, and OAuth to move data cleanly between platforms. I use Python + FastAPI for custom services and specialized data pipelines that move scraped data directly into your CRM or database. 🎯 WHY I'M DIFFERENT FROM OTHER FREELANCERS ✅ QA background — I find bugs and scraping "edge cases" before your clients do. ✅ Resilience focused — I build scrapers that handle anti-bot triggers and IP rotation. ✅ Content writing experience — Clear documentation, clean handoffs, no confusion. ✅ Production mindset — I ask "what happens when this breaks?" before writing a line. 🛠️ TECH STACK Scraping: Playwright, Selenium, BeautifulSoup, Scrapy, Proxy Rotation, Stealth Browsing Automation: n8n, Make, Zapier, Webhooks AI & Agents: OpenAI (GPT-4o), RAG, Agentic Workflows, LangChain Backend: Python, FastAPI, REST APIs, OAuth, Async Processing Data/DB: PostgreSQL, Supabase, Airtable, Pandas, CSV/JSON Pipelines 💬 HOW I WORK ✅ Clear scoping before we start—no surprises mid-project. ✅ QA-reviewed delivery—tested against edge cases, not just the happy path. ✅ Clean, documented, maintainable systems. ✅ Post-delivery support included. 🚀 Ready to build a resilient data pipeline or automate a process?
