N8n automation developer

Hi, I came across your profile and think you might be a good fit for my project. I'm looking for someone with experience in n8n, AI Agents, OpenAI, and MongoDB Chat Memory. I need help configuring and manually testing the memory feature to ensure it correctly stores and retrieves conversation history. The goal is to verify that the AI agent remembers previous user inputs across messages and to resolve any issues if the memory isn't working as expected. Once it's working, I'd also like a brief explanation of the setup so I can replicate it later. Please let me know if you've worked on similar n8n AI workflows and if you're available to help.
