Hubert García Gordon

Specialist, not generalist. C#, ASP.NET WebForms through .NET 9, SQL Server and heavy T-SQL. Enough JavaScript and TypeScript to ship a UI. AI side: Ollama, Qdrant, RAG on-premise.

How to evaluate RAG properly: chunking, embeddings for Spanish clinical text, reranking. On the .NET side, EF Core and minimal APIs, unlearning 20 years of WebForms habits.

ag-onpremise: a self-hosted RAG stack on ASP.NET Core 9, Ollama and Qdrant, for teams whose data can't leave the building. At work, a 300+ page WebForms system moving to .NET 9.

Talk to me about migrating legacy .NET, or about running LLMs on-premise when your data legally can't go to the cloud. Also happy to compare notes with anyone building software for public health.
