Eddy Zhang

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

Portfolio  ·  LinkedIn  ·  Email  ·  Joblit

I build AI-native products where prompts, retrieval, model routing, evaluation, backend reliability, and product UX are treated as one production system. My work sits at the intersection of applied LLM engineering, full-stack product delivery, and cloud-native system 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.
