@khuzaima024

Hi, I have already created a similar type of WhatsApp integration project, I have shown you in chat and you can also check my profile for reference. I can check your current n8n + Supabase setup, identify why embeddings/vector memory are failing, and rebuild a fully working RAG pipeline with OpenAI embeddings. Delivery includes live walkthroughs, optimized vector retrieval, and a complete WhatsApp AI agent ready for scaling. Let Discuss !!

@techstar12

I can audit and fix your n8n + Supabase setup so the RAG pipeline works end-to-end. I’ll review your current workflow and database schema, identify why embeddings/vector retrieval aren’t returning relevant answers, and patch the flow (chunking → embeddings → Supabase insert → retrieval) so your WhatsApp agent consistently pulls from stored context. I’ll also ensure JSON handling and API calls are clean, with inline notes or a walkthrough so you can maintain it. Do you prefer a live screen-share session for debugging/finalization, or would a documented step-by-step handoff be more useful for you?

@yashkumar2104

Hello, I've thoroughly reviewed your project description and believe I'm the ideal candidate for the following reasons: EXPERTISE: I bring strong experience with n8n automation, Supabase, and RAG pipeline design using OpenAI embeddings. I’ve successfully built vector search workflows in n8n with end-to-end integration across Supabase, embeddings, and messaging interfaces like WhatsApp. TAILORED SKILLS: I’ve previously worked on similar systems, where I: Audited and debugged broken vector search flows Designed embedding + chunking pipelines in n8n Integrated OpenAI for semantic retrieval Worked with Supabase vector columns and Postgres JSON Delivered via live sessions and detailed documentation SKILLS: n8n (custom workflows, error handling, modular design) Supabase (tables, APIs, vector extension, Postgres JSON) OpenAI Embeddings & RAG Pipelines WhatsApp Webhook Integration LangChain in n8n API Design & Troubleshooting I'm ready to start immediately and can collaborate via live calls or provide a clear walkthrough post-implementation. I’m also open to long-term collaboration on future n8n projects. Thank you for considering my proposal. I look forward to helping you finalize and scale your AI assistant. Best regards.

Hello, I have strong experience building end-to-end automations in n8n with Supabase, OpenAI embeddings, and RAG pipelines. I’ve previously implemented vector-based memory retrieval, chunking workflows, JSON/API transformations, and WhatsApp webhook integrations, so I’m confident I can quickly audit and optimize your setup. To start, I will first create a detailed project document outlining how I’ll complete each task in scope—covering the current issues, proposed fixes, timeline, required third-party integrations, and cost estimates. This ensures full transparency and clarity before execution. My approach: * Audit & Diagnosis – Review your current n8n workflows + Supabase schema to identify why retrieval is failing. * Fix & Optimize – Implement proper embedding/vector storage, retrieval queries, and chunking strategy. * Integration – Ensure WhatsApp webhook + Supabase + n8n flows communicate seamlessly. * Validation – Run end-to-end tests with real prompts and verify relevant responses. * Handoff – Provide either a live walkthrough (Zoom/Meet) or detailed documentation so you’re fully equipped to extend it. I’ll also suggest optimizations for scaling and maintaining the system beyond this scope. If our collaboration works well, I’d be glad to continue with your upcoming n8n automation projects. Let’s connect and get started immediately.

@kirills31

Hey there, Quick question before we dive in: when you say the retrieval "isn’t working properly," are you getting irrelevant matches from Supabase, or is the embedding/query step silently failing? Also, how are you currently chunking and indexing, pure n8n function nodes or external preprocessing? I've built multiple RAG-style flows using Supabase PGVector + OpenAI + n8n, and one common cause of weak retrieval is poorly normalized chunking or misaligned vector dimensions during upserts. Another is incorrect cosine-similarity ranking due to missing match_threshold logic in the Supabase RPC call. I can walk through your current setup live or diagnose it offline and ensure vector insertions, query embeddings, and match ordering are bulletproof. I'll also tidy up your WhatsApp webhook routing, document the full vector pipeline, and suggest scale strategies like cron-based re-embedding and batching for long documents. If you're using LangChain inside n8n's code node, we can simplify or swap for direct API calls for stability. Looking forward to fixing this fast and clean. Best, Kirill

@adriana621

Hi there! I have solid experience working with n8n automations, Supabase, and OpenAI’s embedding flows. I’ve helped build several RAG pipelines that use vector search for accurate and context-aware retrieval, and I’m confident I can identify what’s going wrong in your current setup. I’d be happy to jump on a screenshare to walk through everything with you, or provide clear documentation—whichever you prefer. Let’s get your WhatsApp AI agent working smoothly and ready to scale. Looking forward to collaborating!

@AlexTuvshyntur

Hi there Is the chunking logic consistent between the input and stored embeddings? How are you currently matching WhatsApp input against stored vectors—via cosine similarity threshold, top-k, or something else? I’ve worked on this kind of n8n + Supabase + OpenAI setup before, and the main issues often lie in embedding misalignment, or vector columns not being updated correctly. I can screen-share to review your current n8n flow and Supabase table schema, then fix the memory logic and test retrieval end-to-end. The hard part here is getting Supabase vector search tuned for semantic similarity. The second is ensuring n8n correctly transforms the WhatsApp text, queries the DB, and returns a smooth reply—all while keeping latency low. I would be happy to discuss further on chat. Best Oleksandr

@brianf0812

Hi, dear client, I can audit your current n8n setup, identify why the embedding/vector memory flow isn’t functioning, and fix it so your WhatsApp AI assistant retrieves relevant answers from Supabase reliably. I’ve built RAG pipelines in n8n using OpenAI embeddings and vector searches, integrating Supabase tables and JSON transformations to deliver fully functional AI retrieval systems. Could you clarify if your current workflow already handles chunking, or should I implement that from scratch? I’m confident I can finalize the system, provide live walkthroughs or detailed documentation, and anticipate giving you a polished, scalable AI agent ready for immediate use. Best regards
