I build AI automation, RAG systems, and web data extraction pipelines connected to real websites, APIs, documents, databases, and backend workflows. My work usually combines three parts: 1. Data collection — scraping, API-first extraction, web automation, document ingestion, and external data integration. 2. AI processing — LLM-based cleanup, classification, summarization, deduplication, enrichment, structured extraction, and reasoning over messy data. 3. Retrieval systems — RAG pipelines for searching, indexing, and answering questions from documents, scraped content, product catalogs, internal knowledge bases, or business records. I work mainly with TypeScript, Node.js, Go, and Python when needed. My usual approach is API-first: inspect the website or system, find the most stable data path, then use browser automation only when necessary. For AI systems, I focus on practical backend workflows, not just prompt demos. Relevant Upwork work includes KTB Automation API, Krungthai Business Bank Middleware Automation, and a recent 5-star website/email function project where the client described me as “a true professional” and said they would continue using my services. Good fit for: AI-powered web scraping and data extraction RAG systems for documents, websites, or internal knowledge bases LLM processing for scraped or messy data Product, marketplace, real estate, lead, or research data pipelines Chatbots connected to custom data sources API-first extraction from websites with hidden or internal endpoints Scheduled scraping jobs with CSV, Excel, Google Sheets, Airtable, or database output Backend automation using Go, Node.js/Bun with TypeScript or Python. I prefer practical systems over AI demos. The goal is clean data, reliable automation, useful retrieval, and a workflow that can be reused. Send the target website, documents, required fields, output format, and whether this is one-time or recurring. I’ll tell you clearly whether I’m the right fit.
