About Me

( 01 )

Senior software engineer based in Brisbane with just over a decade of experience shipping production systems across web, mobile and data infrastructure. As Head of Technology at Holloway Removals & Storage I own the full stack as a solo technical lead — Next.js on Vercel, BigQuery analytics with Fivetran and Airbyte pipelines, integrations across CRM, accounting and telephony platforms, and a production AI voice agent built on the Anthropic API. Equally comfortable as a hands-on builder or setting technical direction for a lean team.
