## Person

- **Name**: David Tran
- **Level**: Senior
- **Summary**: Backend engineer (Senior) focused on robust Python-based ingestion and API backends with extensive, edge-case driven tests. The developer's strongest proven skill is building reliable data ingestion and normalization pipelines, demonstrated by the ingest sources (house_clerk.py, senate_efd.py), parser (ingest/parser.py), store_filing logic (ingest/store.py) and a broad test suite validating edge cases. There is limited public evidence of large-scale distributed operations (message brokers, horizontal worker orchestration), production authn/authz flows, or formal rate-limiting and secrets-management patterns.
