About me

Who I am

I am a Software Engineer based in Melbourne, Australia with 4 years of commercial experience across frontend development, backend integration, software testing, and quality engineering. I have delivered enterprise applications across aviation, global logistics, automotive, and healthcare.

My core strength is React and TypeScript frontend engineering, complemented by hands-on experience with Node.js, Express.js, REST APIs, functional testing, API validation, regression testing, defect analysis, and Agile software delivery.

Most recently, I worked as a Test Engineer at Elenium Automation within the Software Development team, performing end-to-end testing and validation across aviation software and hardware products including passenger processing applications, self-service kiosks, bag-drop systems, web portals, APIs, and backend services.

Previously, I developed frontend experiences for the Mercedes-Benz US digital platform using React, TypeScript, and AEM, and developed enterprise React applications for CMA CGM supporting shipment tracking and operational workflows.

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 worked across four industries — aviation, global logistics, automotive, and healthcare — adapting quickly to complex enterprise environments and collaborating with engineering, QA, product, and business stakeholders.

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