Data & AI Solutions Engineer | Lead Generation & Web Data I build data pipelines and AI-powered tools that turn messy public web data into clean, decision-ready assets — and when it makes sense, into RAG-powered agents that answer questions from that data. What I solve: • Lead Generation at Scale — prospect databases with verified contacts (names, emails, phones, LinkedIn), enriched and deduplicated, ready for your sales team. • Market & Competitive Intelligence — pricing monitoring, product catalogs, review mining, market research. • Document Intelligence — parsing complex PDFs (tables, formulas, mixed-language) into structured Excel/CSV, and into chunked, embeddable formats for RAG. • AI Agents & RAG Pipelines — knowledge-base Q&A agents (WhatsApp, web, internal tools) on vector databases; document ingestion → chunking → embeddings → retrieval → LLM answer, with moderation and audit layers. • Anti-Bot & Hard Targets — Cloudflare, AWS-WAF, aggressive rate limiting: I know when to engineer around it and when to tell you it's not worth it. How I work: • Feasibility-first: I tell you what's realistic before you commit — including when the answer is "don't do this." • Accuracy over volume: every record is verified or clearly flagged. No fabricated data, ever. • Documented & reusable: scripts, schemas, pipelines you can run again without me. • AI done right: generated content is moderated and human-reviewed — I don't ship hallucination-prone outputs. Selected outcomes: • Built a 50,000+ record physician directory from publicly available health registries, deduplicated and URL-verified — delivered as a structured database for client's internal use. • Processed 60,000+ facility records (clinics, hospitals, labs) from an open government registry, with ~85% phone and ~75% email completeness — cleaned, normalized, and export-ready. • Extracted 15,000+ product reviews from a Cloudflare-protected e-commerce site in 3 days with dual-pass validation. • Delivered a 5,000+ record Google Maps enrichment pipeline (phone/website/email matching, 23-28% verified-match rate). • Processed formula-heavy, bilingual PDFs into structured Excel — eliminating days of manual re-entry. Skills: lead generation, prospect list, B2B data, list building, contact enrichment, data scraping, web scraping, Python, Playwright, Selenium, API integration, RAG, vector databases, PDF parsing, data cleaning, data mining, market research Languages: Fluent English & Chinese. Message me with your use case. I'll reply within 24 hours with a feasibility assessment and a realistic plan — including what I can't do, so you never waste budget on false promises.

AI Automation & Python Engineer — production AI agents, browser automation, RAG systems, data extraction pipelines, and backend applications that solve real business workflows. I build production-ready automation and AI systems, not just prototypes. My work combines Python, Playwright, FastAPI, OpenAI/Claude/Gemini, RAG, n8n, APIs, databases, and cloud infrastructure to automate workflows that would otherwise require hours of repetitive manual work. I have 8+ years of experience with Python, web scraping, browser automation, APIs, data processing, and backend development, and I now specialize heavily in AI-powered automation. WHAT I BUILD → AI Agents & Business Automation AI agents that can research, extract data, process documents, make decisions, call APIs, update databases, generate reports, and trigger downstream workflows. Tech includes OpenAI, Claude, Gemini, n8n, Make, Python, FastAPI, MCP, structured outputs, tool calling, and custom APIs. → RAG & Knowledge-Base Chatbots Production RAG systems that answer questions from private company documents and knowledge bases. Typical architecture: Documents → Parsing → Chunking → Embeddings → Vector Database → Retrieval → LLM → Citations I work with FAISS, pgvector, Supabase/PostgreSQL, OpenAI embeddings, Claude, Gemini, and custom retrieval pipelines. → Browser Automation & Web Scraping Complex automation for authenticated portals, dashboards, document downloads, data collection, and repetitive browser workflows. I work extensively with: Playwright • Selenium • Scrapy • requests • aiohttp • BeautifulSoup • lxml Including dynamic JavaScript websites, pagination, authenticated sessions, downloads, retries, proxy infrastructure, and anti-bot environments. → Document & PDF Automation Systems that turn PDFs, receipts, statements, images, spreadsheets, and business documents into structured data. Examples include: PDF/Image → OCR/Vision → Extraction → Validation → Structured JSON/CSV/Excel → Database/API I build workflows for invoices, receipts, financial documents, reports, forms, and large document collections. → Python / FastAPI Backend Systems Production APIs and backend services using: Python • FastAPI • Django • Flask • Celery • Redis • PostgreSQL • MySQL • MongoDB • Docker I can own the complete backend — API design, asynchronous processing, database architecture, background jobs, integrations, logging, testing, and deployment. → n8n / Make / API Automation I automate workflows across CRMs, Google Sheets, Google Drive, email, databases, AI models, internal APIs, and third-party SaaS platforms. When low-code is enough, I use it. When reliability or complexity requires code, I build the missing pieces in Python. RECENT SYSTEMS I’VE BUILT AI Healthcare Research Platform Built a complete pipeline for collecting public patient discussions, extracting symptoms, interventions and outcomes with AI, normalizing thousands of signals, maintaining source-level traceability, and presenting the results through an interactive dashboard. Bank Document Automation Built Python + Playwright workflows for authenticated financial portals where the user handles login/MFA and automation takes over afterward — discovering accounts, downloading historical PDFs, organizing documents, detecting duplicates, and maintaining audit manifests. AI Document Extraction Platform Built systems that accept PDF, Excel and image documents, extract structured information using traditional parsing + OCR/Vision/LLMs, validate the results, and export clean datasets. Large-Scale Web Data Pipelines Built and maintained scraping infrastructure across hundreds of websites with proxy rotation, retry chains, anti-bot handling, automated QA, structured extraction, and production monitoring. AI-Powered Data & Reporting Systems Built structured datasets and semantic layers designed specifically for LLM reasoning, reporting, search, and downstream AI applications.
