Hello 👋, I am a top rated plus business process automation freelancer on UpWork (https://www.upwork.com/freelancers/~014605eb151f2b3dac?mp_source=share) and available for hire. I have experience working with Zapier, n8n, Apps scripts, Replit, Airtable, CRMs, todolists (Notion & Asana the most), Python, Javascript, Neo4j, AWS, GCP, Docker. I can build workflows, AI agents and apps. I have a lot of experience automating document processes (my primary client is a US financial institution). What sets me apart from most other tech people is having an excellent business understanding: I founded and grew a startup to $100K MRR in the past. I cost $75 per hour (non negotiable) and I like tackling hard projects. Reach out if interested!

I'm trying to build an AI Agent consisting of an orchestrator/classifier + sub-agent tools to analyze PDF documents. However, I am not finding how to provide files / refer to them in the Advanced AI node? I have tried mainly with GPT 4.1 as the model. I did upload files via OpenAI API.
