// about me

Building systems that scale.

Senior Software Engineer with 10+ years building scalable backend systems across financial services, banking, online gaming and payments. Currently Tech Lead at VGW, Sydney — one of Australia's leading online gaming platforms.

I specialise in designing systems that handle billions of transactions reliably, architecting microservices for millions of concurrent users, and building testable, maintainable code that teams can confidently evolve.

Right now I'm deep in AI engineering — agentic coding with Claude Code, building RAG pipelines, exploring MCP, and figuring out what production-grade AI actually looks like in Java and Node.js.

Life beyond code.

Engineering the perfect balance — in and out of the water.

🏀
Basketball — All Year Round
Rain, shine, or any season — the court is always calling. Basketball is a non-negotiable weekly ritual. Fast breaks, team play and just enough competitive fire to keep things interesting.
🏊
Swimming
Year-long swimmer at the beautiful Brighton Beach. There's something about being in the water — the rhythm, the quiet, the reset. Rain or shine, the ocean is always calling.
🍜
Foodie
Sydney is a food city and that suits just fine. Always hunting the next great spot — from hidden ramen joints to rooftop dinners. Food is culture, and exploring it is one of life's great pleasures.

Always happy to have a chat.

Always happy to connect — whether it's about an interesting problem, a collaboration, or just a chat about Java, NodeJS, or basketball — or an ocean swim. No pressure, just good conversation.
