    I'm an Engineering Systems & Design undergraduate at the Singapore University of Technology and Design, on the Business Analytics and Finance track, alongside Design and Artificial Intelligence.

    I enjoy mechanical problem-solving, rapid prototyping and systems optimisation. I like turning complex ideas into reliable physical prototypes through 3D printing, computational modelling in Rhino and Onshape, and rigorous testing. I use Python for data processing and technical analysis, and at the Digital Church Office I test the myCatholicSG parish app (React, Firebase and Node.js) before each release, including its SingPass integration.

    Outside university, I teach at SGEducators Tuition Centre, mark essays at Writers' Guild Learning Centre and photograph events, which I've done since 2020. On campus I'm House Secretary of Mythos, Publicity Lead for IEEE and Tech Lead for IES.

    I work iteratively, pay close attention to detail and collaborate well.
