About

I'm a Software Engineer passionate about building impactful solutions that bridge the real and digital worlds. After joining MongoDB as part of their 1st and 2nd Australian internship cohort, I’ve spent over 5 years on the MongoDB Charts team. My recent projects include refactoring a legacy codebase to TypeScript, enabling natural language-driven data visualisations using LLMs and designing a migration framework. I’ve also presented at MongoDB conferences in New York and Sydney sharing insights on our SDK and AI-powered features. Outside of coding, I bring the same curiosity and drive that fuels my engineering work to exploring new hobbies and challenges.
