About

Enterprise experience with a product mindset.

I focus on business outcomes, strong collaboration, and systems that stay maintainable after launch.

I work across the stack using ASP.NET Core, React and Next.js, SQL Server, PostgreSQL, and Supabase. My focus is clear architecture, reliable delivery, and maintainable systems. I'm based in Melbourne, Australia with full work rights and available for full-time software engineering roles.

Most of my commercial work lives in private repositories. In interviews I can walk through scope, technical decisions, and measurable outcomes while respecting confidentiality.

I also build focused public work that demonstrates secure authentication, scalable APIs, and production-ready application architecture.
