Melbourne-based Lead Frontend Engineer with 11+ years building React and Next.js platforms that perform under pressure — live event traffic spikes at Racing.com, secure banking interfaces at ANZ, 56% bundle reduction at Pepperstone.

I believe the best code is the code your team wants to maintain. I obsess over performance, test coverage, and DX because shipping fast means nothing if you can't ship again tomorrow. I've mentored 5+ engineers, led architecture across fintech, media, and banking — and I build with AI as a force multiplier.
