Hey there. If you're meeting my curated digital self, well, nice to meet you. I hope to meet you properly someday.

A simple rundown. I'm interested in, and actively working on, representations, information quality, and the data engineering underneath it. Entity resolution, NER, classification, and digital identity: decentralised, self-sovereign, and the question of who decides your data is yours. In more marketable terms: record linkage, knowledge graphs, semantic layers, and intelligence.

Lately that means AI agents, and whether one understands what it is acting on, and knows when to refuse. That's me.

Notes living, revised

  • A category is a decision The same marketplace, address book, or neighbourhood can be grouped many ways. Somebody chose, for a purpose, and the purpose is still in there. rev. 9 Sep 2026
  • Similarity is not transitive Looking alike can help us find a group. It cannot tell us what the group is for. rev. 7 Sep 2026
  • Sameness and similarity Two records can look alike without referring to one thing. The small distinction that makes matching systems safer. rev. 3 Sep 2026
  • A place is not a point Place is the bridge for anything that has to arrive. Space, place, and the two ways of giving somewhere an identity. rev. 31 Aug 2026
  • What kind of thing are you resolving? The country is real. The strings are not. What that changes for entity resolution, and for systems trying to reason about the result. rev. 7 Sep 2026
