I work at both ends of a product. Schema design, REST boundaries, authentication and query plans at one end. Retrieval pipelines, agent workflows and model inference at the other. On more than one product I have owned all of it alone, from the first migration to the release.

How a question moves06 stages

Plain language in,rows and actions out.

The shape of the retrieval work at Nysonian. Staff ask about the business in plain language, and the answer comes from millions of customer records instead of a SQL query they had to write.

What happens
  1. 01AskA person types a question the way they would ask a colleague.
  2. 02EmbedThe question becomes a vector, with the same embedding model the records were indexed with.
  3. 03RetrieveSemantic search finds the closest records across millions of rows in PostgreSQL.
  4. 04AssembleThe best matches and their table context are ranked and packed into the prompt.
  5. 05AnswerThe model replies in plain language, grounded in the rows it was given.
  6. 06ActLangChain and n8n workflows pick up the follow up and run it in the system that owns it.
