Toh De Kai
Product Driven Engineer
Creating intuitive and impactful digital solutions
About
Back in 2020, I had the opportunity to develop a landing page during my UI/UX internship at Calibrate. This experience ignited my passion for coding, leading me to pursue a Bachelor's degree in Computing.
Since then, I have gained diverse experience across various roles, including project management, UI/UX design, and software engineering. This multifaceted background has equipped me with a comprehensive understanding of the development and design lifecycle, allowing me to deliver high-quality, user-centric digital solutions.
I specialize in creating intuitive, impactful, and accessible web applications. My goal is to bring innovative ideas to life while ensuring an engaging user experience.
When I'm not at my desk, I like to keep myself busy through an active lifestyle - aiming to complete a sub-5 hour marathon in 2025
