Summary

Rockstar🎓
Top SchoolJosh Barr is an engineer with 14 years’ experience helping organisations shift trajectory through pragmatic architecture and hands‑on coding, equally comfortable writing greenfield products or unraveling knotty legacy systems. He combines a visual design background with deep operational experience in event‑driven, serverless and API ecosystems, having architected backends that handle billions of requests and rebuilt healthcare infrastructure serving 7 million patients annually. Josh has shipped developer tooling and docs automation (including an evergreen API docs platform) and contributed full‑stack improvements to the popular Wagtail CMS, blending UX sensibility with scalable backend design. He’s delivered measurable outcomes — zero‑downtime migrations, 43% cost‑to‑serve reduction, 80% lower HL7 ingest costs, and multi‑million dollar savings from feature management — while mentoring teams on distributed systems and interoperability (FHIR/HL7). Based in Wellington, he pairs product focus with production rigor, often building test harnesses and simulation tools that let teams iterate confidently in production.
