Joe Sealey
Applied AI Engineer
I ship LLM-powered products for businesses across New Zealand & Australia — agents, RAG, and evals, plus the production engineering that makes them reliable.
What I do
Frontier AI, shipped to production
12+ years of software and systems engineering, now focused entirely on taking AI from impressive demo to dependable product.
LLM Applications & Agents
Production assistants and autonomous agents — tool use, multi-step workflows, and structured output you can trust.

- Tool use & function calling
- Multi-agent orchestration
RAG, Evals & Data
Retrieval pipelines and evaluation harnesses that keep AI features accurate, measurable, and grounded in your data.
- Retrieval & vector search
- Eval & regression suites
- Observability & tracing
Production & Security
The unglamorous engineering that turns a demo into a dependable product — secure-by-design, at scale.
- TypeScript & Python
- Cloud deploy & CI/CD
- SOC2 / ISO 27001 mindset
