About Me
Hello! I'm Kien — a software developer with 6 years of experience and a strong focus on frontend development. I specialize in crafting responsive, accessible, and high-performance user interfaces that deliver seamless web experiences.
After graduating from the University of Waterloo with a Bachelor of Science in Biochemistry, I found myself working in a costing role where I spent most of my time in Excel spreadsheets.
While the job wasn't related to my degree, it was there that I discovered a passion for problem-solving through automation — I started using VBA to streamline repetitive tasks, and that experience ignited a deeper curiosity about programming.
Motivated by that spark, I made the decision to leave and pursue a self-taught path into software development. Since then, I've been committed to continuous learning and growth, staying at the forefront of frontend technologies to build fast, accessible, and user-friendly applications.
