Reliability
Source inspected
A broken source should not block every other source.
Independent source processing, deadline handling, stable identifiers and health records support multi-source ingestion.
01 THE PROBLEM
What needed to change
Upstream sources change formats, fail independently and return incomplete records. A slow source can stall discovery and inconsistent identifiers can duplicate records.
02 THE IMPLEMENTATION
What I built and directed
I directed a multi-source ingestion path with independent settled outcomes, per-source 30-second deadlines, isolated diagnostics and source-health records. Adapter logic handles an upstream API version and records parser and retrieval provenance. Canonical external identifiers support matching and update/backfill behaviour.
03 THE CHECK
What the evidence establishes
Current source inspected on 9 October 2026, including per-source deadlines, parser provenance, source health and canonical matching.
Scope of this example
Source-isolated ingestion with deadlines, provenance and health records. Cancellation and identifier fallback are the next reliability checks.
04 THE LESSON
The judgement behind the code
Diagnose each source separately. Keep incomplete records and upstream failures visible rather than reporting a misleading clean aggregate.
