Hi, Your project to turn business conversations into actionable insights is exactly the kind of challenge I’ve tackled before. At a healthcare AI startup, I built production-grade LLM pipelines that processed recorded patient calls — converting speech to text, generating structured summaries, and flagging key concerns using FastAPI microservices. This included implementing RAG workflows with embeddings and vector search for better retrieval, plus monitoring and evaluation tools to handle hallucinations and optimize costs. A few questions to align on your needs: - Are you focused on specific conversation types or industries? - Do you prefer certain vector databases or cloud platforms for hosting? - What latency targets do you have for real-time inference? I can help design a scalable architecture that balances speed, cost, and accuracy, with Dockerized deployments for robust system reliability. Let’s jump in and start refining your AI pipeline for production readiness. Ready to get going when you are.

Hello Mark, I’m a software services provider with real production experience shipping LLM systems—not demos. I’ve built end-to-end speech → text → insights pipelines, RAG with embeddings/vector DBs, and low-latency FastAPI microservices running in Docker on cloud. I can show demo code + production patterns (evals, guardrails, cost controls) before we lock the deal. What I’ll Build for You (Production-Grade) 1) Conversation → Intelligence Pipeline • ASR (Whisper/Deepgram) → diarization → chunking • LLM summarization, classification, objection detection • Structured outputs (JSON schemas) + PII handling 2) RAG @ Scale • Embeddings (OpenAI/BGE), vector DB (FAISS/Pinecone) • Reranking, caching, eval harness (precision@k, win-rate) • Hallucination controls + prompt/versioning 3) FastAPI Microservices • Async inference, retries, rate limits • Cost/latency optimization (batching, caching) • Monitoring (traces, eval dashboards), CI/CD, Docker Tech Stack Python · FastAPI · OpenAI/Claude/Gemini · LangChain/LlamaIndex · FAISS/Pinecone · Docker · Cloud Relevant Projects CallSense AI – speech → insights for sales calls InsightRAG – embeddings + rerank + eval framework FastServe AI – low-latency LLM microservices If you want someone who ships, debugs hallucinations, and designs for failure paths first—I’m in. Share your current stack and data flow; I’ll propose a phased rollout and we’ll make the deal.
