About
Backend and full-stack engineer building practical software with clear interfaces.
I'm Reilly Oldham, a software engineer in Wellington, New Zealand. I work across backend systems, observability, developer tooling, and product interfaces, with recent experience building distributed agent infrastructure, Raygun observability features, public transport apps, and technical writing.
I like turning ambiguous engineering problems into working software with explicit boundaries, useful failure states, and interfaces that make the underlying system easier to reason about.
