What this proves

Production AI, 3 years running

Expat Money's compliance system has been in production since 2023 — deterministic validation, LLM explanation, traceable decisions. Not a demo.

24 public repos, built in the open

Every repo is public. Every project page links to source. You can inspect the code, the tests, the architecture — nothing is hidden behind a private org.

Systems thinking, not feature work

Five-service architectures, agent frameworks, observability SDKs, RAG evaluation harnesses — the repos form a coherent system, not a scattered portfolio.
