About

Started with being an Engineering Management Associate in SMRT, which manages one of the world's top public transport system, I have gained experience in maintaining and operating Rolling Stock and Train-borne Signalling and Communication systems. My involvement in Thomson-East Coast Line has also allowed me to collaborate with multiple contractors from different countries. As a highly-motivated learner who is interested in engineering and technology, I have also never stopped taking initiative to experience multi-disciplinary development and ensure adaptability in dynamic environments even after graduation, exploring fields ranging from aerospace to railway engineering and data science (artificial intelligence). I also take part in voluntary activities during free times to help others whenever possible.
