If your team is stuck doing manual work, buried in spreadsheets, or struggling to collect data from sites nobody else could figure out - I build the system that fixes that. I specialize in Python automation, large-scale web scraping, data pipelines, and AI integrations. I've delivered 100+ projects including extracting 10,000+ product records from Amazon and Kohls, building scrapers for Cloudflare-protected platforms, and developing AI-powered backend workflows that run 24/7 without babysitting. Here's what I can build for you: • Web scraping systems — Scrapy, Playwright, Selenium, BeautifulSoup. Handles dynamic JavaScript-heavy sites, login-gated pages, anti-bot detection, rate limiting, pagination, and proxies. If a site has data, I can get it. • Data pipelines — Full ETL pipelines that extract, clean, deduplicate, and deliver structured data into PostgreSQL, MongoDB, CSV, Excel, or directly into your app. • API integrations — Connect third-party services, build REST API backends with FastAPI, Flask, or Django, and wire up webhooks and automation triggers. • AI agent workflows — OpenAI API, Claude, LangChain, RAG pipelines, and vector databases. I build intelligent automations that replace repetitive decision-making, not just repetitive clicking. • Workflow automation — n8n, Make, Zapier, or custom Python. Automated pipelines that handle lead generation, data mining, data extraction, and reporting without manual input. I work on ongoing projects and one-time builds. My systems are production-ready, with retry logic, error handling, monitoring, and documentation - so they keep running long after I've delivered them. 100% Job Success Score | 5.0★ rating | Top Rated MY STACK Scraping: Python, Scrapy, Playwright, Selenium, BeautifulSoup, Puppeteer, Proxies, Anti-bot Bypass Backend & APIs: FastAPI, Flask, Django, REST APIs, Webhooks, JavaScript AI & LLM: OpenAI API, Claude, Gemini, LangChain, LlamaIndex, RAG, Vector Databases, AI Agents Automation: n8n, Make, Zapier, ETL Pipelines, Data Mining, Data Extraction, Lead Generation Databases: PostgreSQL, MongoDB, MySQL, SQLite, CSV, JSON, Excel Cloud: AWS, GCP, Docker, Kubernetes, Lambda, EC2, Cloud Run If this sounds like what you need, send me a message or shoot me an invitation, I'll jump on a quick call or send back a Loom video walking through how I'd approach your project.
