Symfony AI Knowledgebase & Chat. 251217

@AwaisChaudhry

Hello, I’m Muhammad Awais, ready to turn your Symfony 8.x backend idea into a solid, scalable knowledgebase with a streaming chat UI. My plan is to deliver in clear phases: 1) backend: document ingestion, embeddings pipeline, and a robust DB schema; 2) a modular LLM integration layer that can switch between OpenAI, Gemini, Claude via config; 3) a frontend chat that streams messages and stays memory-friendly; 4) a lazy, incremental indexing and caching strategy to keep answers grounded to source pages; 5) docs, tests, and GitHub-ready repo. For libraries, I’d use Symfony Messenger for async workflows, Doctrine for data, Mercure for live updates, and a vector store integration (like Pinecone) or other providers; a clean ingestion pipeline with progress feedback and error handling; and a small, responsive UI to keep RAM usage low during long chats. Deliverables align with your list: Symfony project with DB schema, doc ingestor, and embeddings; chat UI connected to LLM endpoints; README with local setup and env vars; a test script or Postman collection; and a GitHub-ready repo. I’ll ensure bulk upload of 10+ PDFs, source citations per answer, easy model switching, and stable memory in long conversations. What vector store and hosting do you prefer (Pinecone, Weaviate, or others), and any data residency constraints? What is your preferred UI approach or framework for the chat surface, or should I build a lightweight responsive UI from scratch? What is your policy for managing mo

Hello, I have hands-on experience building AI-powered knowledgebases and chat systems on Symfony 6/7 with PHP 8.x, including document ingestion, vector search, and streaming chat UIs. I clearly understand your goal: a grounded, memory-safe AI chat over bulk-uploaded PDFs with swappable LLM providers. How I would structure this: Symfony architecture: Clean hexagonal setup with services for ingestion, embeddings, retrieval, and chat orchestration PDF ingestion: Async bulk upload using Symfony Messenger + queues, PDF parsing (page-level chunks), progress feedback, retry-safe jobs Vector store: Pinecone or Qdrant (abstracted via an interface so it’s provider-agnostic) LLM providers: Strategy pattern for OpenAI / Gemini / Claude (config-driven, UI toggle only) Chat streaming: Mercure or SSE to stream tokens safely and keep browser memory stable Grounding & citations: Retrieval-augmented generation with page-level source references I’ll commit directly to your GitHub repo, include a clear README, and provide a Postman collection for end-to-end testing. Happy to discuss final library choices and timelines.

@shanec35

I’ve built AI knowledgebases and internal tools in PHP 8 and Symfony, including document ingestion pipelines and chat-style UIs backed by vector search. I’ve implemented PDF parsing, chunking, and embeddings using Symfony Messenger for async processing and vector stores like Pinecone, Qdrant, and OpenSearch to keep answers grounded in source text. I’ve integrated OpenAI APIs with clean provider abstractions, making it easy to switch between GPT, Gemini, and Claude via configuration instead of rewrites. I’ve delivered streaming chat interfaces using Mercure and SSE to avoid browser memory leaks even in long conversations. I’ve built reliable bulk-upload flows with drag-and-drop, progress tracking, and graceful error handling for large document batches. I would structure this with a Symfony service layer for LLM providers, Messenger for ingestion jobs, and a clean toggle-based UI for model selection. I can start the project right now.
