Senior Python developer specializing in AI agents, RAG chatbots, and large-scale web scraping. I've shipped systems that extract 80M+ records, run 15K+ daily social-media scrapes, and power RAG chatbots with LangChain, OpenAI, and Pinecone for clients in the US, UK, Canada, Australia, UAE, and Europe. What I build for clients: - AI Agents & RAG Systems — Production chatbots and agentic workflows using LangChain, LangGraph, CrewAI, LlamaIndex, OpenAI, Claude, and Gemini. Custom knowledge bases, vector search (Pinecone, Weaviate, pgvector), and retrieval pipelines that actually ground answers in your data. - Enterprise Web Scraping — Scrapy, Playwright, and Puppeteer-based extraction that handles Cloudflare, DataDome, PerimeterX, CAPTCHAs, and aggressive anti-bot systems. Proxy rotation, residential IPs, headless browser fingerprinting, and 100+ elements/second throughput. - Automated Data Pipelines — End-to-end ETL with Airflow, cron jobs, and cloud-native infrastructure. Clean, deduplicated, enriched data delivered to PostgreSQL, S3, Google Sheets, or your API. - Social Media Scraping — Daily extraction from TikTok, Instagram, Facebook, X/Twitter, Kuaishou, and Weibo at 15,000+ posts/day with dashboards and alerting. Selected results: - Built a distributed scraping system that collected ~80M property records from Zillow with zero IP bans and 99%+ data quality. - Shipped a HR knowledge-base chatbot (LangChain + Pinecone + GPT-4o) that cut internal support tickets by ~40%. - Automated daily social-media ingestion across 7 platforms for an influencer-analytics product — 15K+ posts/day, fully unattended. Industries I know well: fintech, healthcare, e-commerce, HR tech,eal-estate, BFSI, manufacturing, and creator-economy / influencer platforms. Tech stack: - Languages: Python, JavaScript / TypeScript, SQL - AI / LLMs: OpenAI (GPT-4o, GPT-4.1, o3), Anthropic Claude (Sonnet, Opus), Google Gemini 2.5, open-source (Llama 3, Mistral, Phi-3, Gemma via Ollama) - Agent frameworks: LangChain, LangGraph, CrewAI, AutoGen, LlamaIndex - Vector DBs: Pinecone, Weaviate, pgvector, Chroma, Qdrant - Scraping: Scrapy, Playwright, Puppeteer, Selenium, BeautifulSoup, httpx, aiohttp, PyMuPDF, Tesseract OCR - Data: PostgreSQL, MongoDB, Redis, Pandas, Polars - Cloud & DevOps: AWS (Lambda, EC2, ECS, S3), GCP, Azure, Docker, GitHub Actions, Nginx, Cloudflare - Generative media: DALL·E 3, Stable Diffusion, Midjourney How I work: ✔ Free 30-min discovery call before any quote — we scope together so the estimate is realistic. ✔ Clean, commented, documented code. You own the repo. ✔ Daily async updates (Slack, Loom, or your tool of choice). ✔ Free POC / demo on larger engagements so you can validate fit before committing budget. ✔ Honest timelines. If something will take longer, I tell you on day one — not on deadline day. If you're building an AI product, scraping data at scale, or automating a workflow that's eating your team's time, send me the brief. I'll come back within a few hours with questions that help us both decide if we're a fit. — Jay (JD), Senior Python + AI Developer
