What I'm looking for

I'm targeting an AI Engineer role at FINXL in Sydney, focused on agentic AI, MCP integrations, retrieval, and cloud-native production systems.

At AETHRUM PTY LTD, I independently architected and built an AI platform from first principles, taking ownership from frontend and backend engineering through integrations, deployment, and production hardening.

I built its agentic architecture around specialist agents, context-aware routing, tool invocation, and multi-step workflows. MCP integrations and external service connectors let agents interact with real systems beyond text generation.

I designed execution controls with approval flows, durable receipts, and safe failure behavior, keeping human approval boundaries explicit. I also implemented model-routing and fallback concepts across commercial and open-model infrastructure.

I work primarily with TypeScript, Node.js, PostgreSQL, and Supabase, and have deployed and operated across Cloudflare and Railway. My background also includes customer-facing IT and commercial roles, including national sales leadership at NSN Infotech.
