With over 6 years of experience in full-stack software engineering, I have delivered high-impact solutions across a variety of industries. I have empowered and led teams using Agile and Extreme Programming practices, with a strong emphasis on creating value for both businesses and users. Having closely collaborated in cross-functional teams across Singapore, the UK, Australia, and Japan, I believe that clear communication and strong integration within and across disciplines is crucial in building resilient teams that deliver exceptional results. I believe in value-centred and people-centred work, and I get excited about opportunities to create huge positive impact with great learning and growth opportunities for myself and others.
