Hire the Best Scrapy Developers
in the United States

I build the unglamorous data layer most founders don't want to touch: web scrapers, data pipelines, data cleanup and enrichment, and small AI automations. And I ship fast, with a working sample instead of promises. A few things I've built: • A scraper pulling product pricing across 14 states into a live, filterable dashboard • A tool that turns messy Confluence spaces into clean, agent-ready docs (markdown, stable anchors, llms.txt) • A Hyperliquid wallet PnL analyzer, and a Meteora DLMM impermanent-loss backtester • codexplays.games, autonomous AI agents I run in public What I'm best at: getting data out of stubborn sites (Playwright, Selenium, requests), cleaning and structuring it, wiring it into Postgres, Sheets, or APIs, and automating the boring parts. Stack: Python, Playwright, Pandas, Supabase/Postgres, plus LLM and agent tooling when it earns its place. How I work: I'd rather show you a working sample than talk. Send me the site or the data problem and I'll usually hand back a small proof before you commit to anything. Fast turnarounds, clean handoffs, and I'm honest about what's actually doable.

Hire me if you need: • Specialized reverse engineering that your backend developers struggle with • SaaS integrations without access to their API • Discord Bots (I am an avid and long-time Discord developer) I might not be the right choice if you need: • Simple web scraping on a budget

Custom AI Agents, RAG Pipelines, & Intelligent Workflow Automation Are you looking to: - Eliminate repetitive manual tasks and cut operational costs? - Build a cutting-edge AI product or scale a SaaS MVP? - Integrate LLMs directly into your existing business software? Most clients come to me with the same problem: a powerful LLM idea but no reliable Python backend to ship it. That is exactly where I help. I design clean, scalable Python systems, wire them into LangChain with full LangChain agent support, LangChain tool calling, LangChain memory, and LangChain Expression Language — then ground every LLM response in your data through a well-tuned RAG retrieval layer so answers stay accurate instead of hallucinated. Core Technical Expertise: Generative AI and LLM Systems: OpenAI API, Anthropic, Llama, LangChain, LlamaIndex, LLM prompt design, LLM call logging, and LLM cost optimization AI Architecture: RAG (Retrieval-Augmented Generation), Autonomous AI Agents, Agentic AI workflows, and Vector Databases including Pinecone, ChromaDB, and Milvus Python Backend and APIs: FastAPI, Flask, REST APIs, Webhooks, and custom Python integrations Data and Workflow Automation: Web scraping with BeautifulSoup, Selenium, and Scrapy; workflow automation with Celery, Zapier, Make, and Crontabs Cloud and DevOps: Docker, AWS, GitHub Actions, PostgreSQL, and MongoDB What I Can Build With Python, LLM, RAG, and LangChain: Autonomous AI Agents — custom LangChain agents that reason, use tools, browse the web, and execute multi-step Python workflows without constant supervision. Full Agentic AI pipelines built in Python with LangChain tool calling and LangChain memory for persistent, stateful automation. Enterprise RAG Systems — production RAG knowledge bases that chat with your private PDFs, CSVs, and databases. A tuned RAG retrieval layer keeps every LLM answer grounded in your data, with high retrieval accuracy and minimal hallucinations. Every RAG system is evaluated for retrieval quality before delivery. SaaS MVPs — rapid Python and LangChain builds of LLM-powered products, taken from a blank repo to a validated, revenue-ready MVP with clean Python architecture and scalable RAG pipelines. Business Automation Pipelines — Python services powered by LangChain and LLM integrations that connect your CRM, Slack, Discord, and internal databases to automate lead nurturing, reporting, and data entry end to end. Intelligent Document Processing — LangChain and LLM-driven extraction, classification, and analysis of invoices, resumes, and legal documents, backed by a RAG index for instant, accurate search and retrieval. Why Work With Me? I pair a business-first mindset with clean, modular Python architecture. Every LLM system I deliver uses FastAPI, proven LangChain patterns, and a well-evaluated RAG retrieval layer so your Python LLM automation keeps performing as your business scales. Every LLM call is logged, monitored, and cost-optimized. You receive transparent communication, clear documentation, clean Git commits, and full end-to-end delivery from Python API integration to cloud deployment on AWS with Docker. I have shipped Python, RAG, and LangChain systems that cut manual work, replaced brittle scripts with reliable LLM pipelines, and turned static documents into searchable, conversational RAG knowledge bases. Whether you need a single LangChain agent, a full RAG platform, or a complete LLM-powered SaaS backend in Python — I deliver Python code you can trust and scale. Click Invite to Job and let us discuss your Python, LLM, RAG, or LangChain project on a quick discovery call.

I build web scrapers that don't get blocked and don't break. 🛡️ If you've watched your bot get banned within minutes of hitting a site behind Cloudflare, DataDome, or Akamai — or inherited a brittle Selenium script that dies the moment the site changes — that's the problem I solve. I build data extraction systems designed to run for months, not days. 🔧 WHAT I BUILD High-volume scraping systems for: • E-commerce pricing & product data • Real estate listings • Business directories & lead generation • Contact extraction 🎯 THE HARD TARGETS This is where most scrapers fail and mine don't: • JavaScript-heavy SPAs, dynamic content, and infinite scroll • Login-gated pages • Serious anti-bot protection — Cloudflare, DataDome, Akamai, PerimeterX, CAPTCHA solving Where it's faster and more stable, I skip the headless browser entirely and reverse-engineer the site's internal API. For ongoing collection, I build scheduled crawlers with proxy rotation, session management, and browser fingerprint handling baked in. 💡 WHY CLIENTS HIRE ME Most scrapers on Upwork work once — on the developer's machine, on a good day. Mine ship with: • Retries, error handling, and failure alerts • Monitoring and scheduling, deployed on AWS or Docker — no babysitting • Clean, structured output: JSON, CSV, straight into PostgreSQL, or via a FastAPI endpoint — not a folder of messy HTML You'll also always know where the project stands. I communicate in plain English, flag risks early, and deliver fast. ⚙️ TECH STACK Python • JavaScript/TypeScript • Playwright • Selenium • Puppeteer • Scrapy • BeautifulSoup • FastAPI • Celery • Redis • Docker • AWS (EC2, Lambda, S3) • GitHub Actions Need the output AI-ready? I deliver structured data formatted for LLM and RAG ingestion. 📩 SEND ME A SITE Even one that's blocked every scraper you've thrown at it.
