Background

About

I was born in New Caledonia. In 2022, straight out of high school, I moved to France to study at Guardia Cybersecurity School, and came out with a bachelor's degree in development focused on cybersecurity.

I then moved back to New Caledonia, where I worked as a web developer at Quantiq until December 2025. Business management applications for companies in very different industries, mostly in PHP and JavaScript.

Since January 2026 I have been living in Australia. I build my own products, including an automation platform for Australian small businesses, and I take on contract web development.

Security changed the way I write code more than I expected. In practice: I never trust what comes from the browser, I hash passwords before writing the first page, and I assume an account will be compromised eventually. It costs a few hours at the start of a project. It saves many more later.
