A bit about me

I'm a Senior Fullstack Developer based in Sydney's Northern Beaches. I specialise in building production-grade web applications, landing pages, and Web3 products for Australian businesses and startups.

Before switching to engineering, I spent years as a senior accountant at EY. That background shapes how I work — I think in systems, measure what matters, and take deadlines seriously.

I work with Next.js, React, TypeScript, Supabase, Node.js, Python, and Solidity. When I'm not building, I'm surfing the Northern Beaches.

The switch from accounting to engineering wasn't accidental — I genuinely wanted to build things. That mix of financial rigour and product thinking tends to come in handy when scoping what's actually worth building. I work best with founders and small teams who need a technical partner, not just a pair of hands.
