Dan Weaver

Applied AI / RAG engineer, 30 years in data systems on C#/.NET and SQL Server. Retrieval quality is the thing I care about: embedding models and dimensions, chunking strategy, hybrid ranking and fusion weights, cross-encoder reranking, and the telemetry that tells you which change actually moved the needle. I run retrieval in production on Azure SQL native VECTOR with DiskANN, Qdrant, and ONNX Runtime, mostly from .NET, which is a corner of this ecosystem almost nobody publishes for. Remote, US.
