About me

bio

I'm an engineering leader and startup founder with over 14 years of experience building software products. My background spans engineering leadership at Xero, co-founding Spotrisk (eCommerce fraud detection), and building teams that ship continuously.

Currently at Prosaic, I'm hands-on in a small team building AI-native accounting software — architecting auth, core APIs, MCP integration, and agentic workflows. AI is deeply integrated into both how we build and what we ship.

Whether I'm writing code, leading teams, or shaping strategy, I care most about bringing people, process, and technology together to build things that matter.

Let's connect.

Always open to chatting about engineering, AI-native products, or collaboration opportunities.
