25+ years of software development experience

I’m a principal software engineer based in Sydney, Australia.

I have more than 20 years of PHP experience, with expert knowledge of PHP 8 and Symfony for web applications, APIs and backend systems.

My experience includes backend platforms powering data on more than 100,000 global companies, helping retail investors make informed decisions.

My work connects architecture, production operations and commercial needs: GraphQL federation, billing and subscriptions, infrastructure security and platform interoperability.

I also build agentic AI software with Python and Pydantic AI, bringing a platform engineer’s perspective to a fast-moving field.
