01.About Me

My colleagues call me "Rin" - a tech savvy with a demonstrated history of working in the tech, pursuing Master of Data Science degree at Swinburne University of Technology. Love keeping my brain up to date with the latest technologies. My love quote is

Throughout my career, I have been fortunate to work in dynamic environments, including AI-based product companies and crypto firms. These start-ups, filled with exceptional colleagues, shared a common vision of breaking down barriers and making AI and revolutionary financial services accessible to all. Currently, my main focus revolves around developing user-friendly features, providing crypto financial services, offering valuable UI/UX feedback, and maintaining an extensive design system consisting of over 40 widely-used components across various projects.

Here are a few technologies I've been working with recently:
