AI Automation

Summary I need an experienced automation and AI engineer to build two connected pipelines for a chatbot RAG knowledge base integrated with a Python FastAPI backend. Part 1 – n8n Web Scraping & Pinecone Sync Build n8n workflows that scrape target websites on a daily schedule, write structured data to Google Sheets, detect changes, then chunk, embed (OpenAI embeddings), and upsert to Pinecone automatically. Must include error handling, failure logging, and a FastAPI endpoint for sync triggering. Part 2 – Document Upload UI & Pinecone Ingestion Build a simple UI for uploading PDF, Word, and Excel files. On upload, extract and clean text, chunk it, generate OpenAI embeddings, and upsert to Pinecone via the FastAPI backend. Upload status and confirmation required. Requirements n8n workflow automation, web scraping (HTTP Request, HTML Extract nodes), Pinecone ingestion pipelines, Python/FastAPI, document parsing (PyMuPDF, python-docx, openpyxl), Google Sheets API, OpenAI embeddings. Deliverables n8n workflow JSON files, FastAPI endpoints, document upload UI, parsing/chunking logic, Pinecone upsert logic, and full setup documentation. Experience with RAG pipelines and connecting n8n to Python backends is strongly
