AI full-stack engineer building production LLM systems
Sydney, Australia · RAG · LLM agents · eval-driven prompting · Spring Cloud · Next.js

Portfolio  ·  LinkedIn  ·  Email  ·  Joblit

I ship LLM systems end-to-end — retrieval, evaluation, model routing, and the backend that serves them — across applied LLM engineering, full-stack delivery, and cloud-native design.

Current focus
RAG-powered agents, portable AI skill packs, eval-driven prompting, and multi-provider LLM orchestration.
Engineering base
Java / Spring Cloud services, TypeScript frontends, Postgres-backed product systems, and CI/CD delivery.
Operating style
Ship useful software, keep model behavior observable, and turn fragile prompt glue into reusable systems.
