About me

Who I am

I am a Software Engineer based in Melbourne, Australia — open to opportunities nationwide including Sydney, Brisbane, and remote — with 4 years of commercial experience building scalable, high-performance web applications for enterprise clients across aviation, global logistics, and automotive industries.

My core strength is React and TypeScript frontend engineering, but I work comfortably across the stack — integrating complex REST APIs, designing component architectures, and shipping production-ready applications independently from idea to deployment.

Currently at Elenium Automation, I built VYGR entirely from scratch — a configuration platform now used daily by Qantas, Virgin Australia, and Jetstar to manage their airport kiosk and bag drop interfaces. I also contribute to the Flight Deck Portal, a real-time operational monitoring tool used by airport teams across distributed kiosk infrastructure.

Previously I owned vehicle detail and homepage pages for the Mercedes-Benz US global platform, and built the Vessel Container UI for CMA CGM — mission-critical operational software handling millions of container movements worldwide.

Outside of work I built PrepTrack, a live AI-powered interview preparation tool using Next.js 14 and OpenAI APIs — designed, engineered, and deployed to production completely solo from concept to launch.

Across my career I have delivered across four distinct industries — aviation (Elenium Automation, serving Qantas, Virgin Australia, Jetstar, and Singapore Airlines), global logistics (CMA CGM via Infosys), automotive (Mercedes-Benz US via SGA Inc), and healthcare (CVS Aetna, one of the largest US health insurance providers, via Infosys). This cross-industry experience means I adapt quickly to new domains and understand how enterprise software works in complex, regulated environments.

I use AI development tools daily — Claude Code, GitHub Copilot, Cursor — and I am passionate about staying at the forefront of modern engineering practices.
