Software & AI Engineer

I build dependable AI agents, regulatory intelligence and data platforms for Australian energy.

About

I’m a software and AI engineer at Outpost Ventures, where I work across products for regulatory intelligence, document workflows and energy operations.

My work spans system design and hands-on delivery: durable agent execution, backend APIs, data pipelines, retrieval systems and AWS infrastructure. I care most about making complex software explicit, observable and reliable enough to use in real decisions.

Before moving into product engineering, I worked with National Electricity Market data and energy forecasting. That domain experience still shapes how I build software today.

Selected work

Most of my work is private production software. These are brief descriptions of systems I’ve helped design and build.

RegLink

Regulatory intelligence

Built regulatory discovery and review workflows, then added evidence-grounded summaries and agent chat that can search initiatives, retrieve source documents and return enriched citations.

  • TypeScript
  • Vue
  • NestJS
  • LangGraph
  • PostgreSQL

Verify

AI-assisted assessment

Designed two durable asynchronous AI workflows for chat and document assessment, with persisted checkpoints, streamed progress, structured results and fail-closed citation validation for AER determinations.

  • TypeScript
  • Vue
  • NestJS
  • LangGraph
  • PostgreSQL

DocForge

Document and knowledge platform

Built an idempotent acquire, index and publish pipeline for canonical documents and reusable knowledge bases, with bounded PDF and spreadsheet processing and retained source provenance.
