Current Employer• Design and build production RAG pipelines — document ingestion, embedding model selection and benchmarking, pgvector storage, and hybrid SQL + vector retrieval over permission-scoped data via FastAPI.
• Harden retrieval reliability with chunking and retrieval-window strategies, hallucination guardrails, confidence scoring, semantic caching, and async LLM query handling through Redis + Celery.
• Own AI infrastructure end-to-end — LoRA/QLoRA fine-tuning on domain data, vLLM deployment with GPU tuning and failover, versioned prompt architecture, and Prometheus + Grafana observability across GPU, API, DB, and sync layers.
