The problem
Production voice assistants frequently struggle with hallucinated outputs, slow multi-step tool resolution, and brittle failure modes when primary LLM APIs encounter rate limits or latency spikes.
The engineering
Engineered a high-concurrency FastAPI streaming service pairing LangChain agentic workflows with ChromaDB vector search for context-grounded retrieval.
Implemented strict AI guardrails, output validation schemas, and automated fallback degradation between OpenAI and Anthropic models to guarantee reliability under heavy traffic.
Designed structured prompt templates and multi-step intent resolution pipelines, backed by CI/CD regression suites evaluating safety, factual accuracy, and p95 latency.
The outcome
Delivered a production voice AI platform grounded in retrieved context, with guardrails, monitoring, and automated fallback between model providers to hold up under real traffic.
