About Me
I'm a Melbourne-based Senior Frontend Engineer with 11+ years turning complex requirements into fast, reliable React and Next.js platforms. From handling 100K+ concurrent users on Racing.com's live event days, to shipping secure banking interfaces at ANZ, to cutting Pepperstone's bundle size in half — I build the kind of frontends that perform under pressure.
I believe the best code is the code your team actually wants to maintain. I obsess over bundle size, test coverage, and developer experience because shipping fast means nothing if you can't ship again tomorrow. I've mentored 15+ engineers and led frontend architecture across fintech, media, and banking — because great products start with great teams. I also build with AI as a force multiplier — integrating LLM APIs into product features, applying prompt engineering in production, and using Claude Code and Cursor to ship faster and smarter.
